A flaw was found in gnutls. The PKCS#7 padding check, performed during decryption, was not constant-time. This timing side-channel could allow a remote attacker to potentially leak sensitive information about the padding bytes through observable timing differences. This vulnerability is a form of information disclosure.
CVE-2026-3832 2 Gnu, Redhat 10 Gnutls, Cert Manager, Discovery and 7 more 2026-09-29 3.7 Low
A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted Online Certificate Status Protocol (OCSP) response during a TLS handshake. Due to a logic error in how gnutls processes multi-record OCSP responses, a client with OCSP verification enabled may incorrectly accept a revoked server certificate, potentially leading to a compromise of trust.
CVE-2025-6170 2 Redhat, Xmlsoft 12 Cert Manager, Discovery, Enterprise Linux and 9 more 2026-09-29 2.5 Low
A flaw was found in the interactive shell of the xmllint command-line tool, used for parsing XML files. When a user inputs an overly long command, the program does not check the input size properly, which can cause it to crash. This issue might allow attackers to run harmful code in rare configurations without modern protections.
CVE-2026-48864 2 Opensuse, Redhat 22 Libsolv, Cert Manager, Discovery and 19 more 2026-09-29 7.8 High
A flaw was found in libsolv. This heap buffer overflow occurs during the decompression of attacker-controlled compressed data within `.solv` files due to insufficient input validation. An attacker can provide a specially crafted `.solv` file, which, when processed by a vulnerable application, can lead to out-of-bounds memory access. This could result in information disclosure, alteration of program execution, or a denial of service.
CVE-2026-42015 1 Redhat 15 Cert Manager, Discovery, Enterprise Linux and 12 more 2026-09-29 5.3 Medium
A flaw was found in gnutls. An off-by-one error exists in the PKCS#12 bag element bounds check. This vulnerability allows an remote attacker to write past the internal array of a PKCS#12 bag when appending to a bag that already contains 32 elements. This memory corruption could lead to a denial of service (DoS) or potentially other unspecified impacts.
CVE-2026-42014 2 Gnu, Redhat 16 Gnutls, Cert Manager, Discovery and 13 more 2026-09-29 6.6 Medium
A flaw was found in GnuTLS. The `gnutls_pkcs11_token_set_pin` function, used for changing the Security Officer PIN, can lead to a use-after-free vulnerability. This occurs when an attacker attempts to change the PIN with a NULL old PIN for a token that lacks a protected authentication path.
CVE-2026-42013 2 Gnu, Redhat 16 Gnutls, Cert Manager, Discovery and 13 more 2026-09-29 8.2 High
A flaw was found in gnutls. When validating certificates, an oversized Subject Alternative Name (SAN) could cause the validation process to incorrectly fall back to checking the Common Name (CN) field. This could allow a remote attacker to bypass proper certificate validation, potentially leading to spoofing or man-in-the-middle attacks.
CVE-2026-42011 1 Redhat 15 Cert Manager, Discovery, Enterprise Linux and 12 more 2026-09-29 7.4 High
A flaw was found in gnutls. This vulnerability occurs because permitted name constraints were incorrectly ignored when previous Certificate Authorities (CAs) only had excluded name constraints. A remote attacker could exploit this to bypass critical name constraint checks during certificate validation. This bypass could lead to the acceptance of invalid certificates, potentially enabling spoofing or man-in-the-middle attacks against affected systems.
CVE-2026-42012 2 Gnu, Redhat 16 Gnutls, Cert Manager, Discovery and 13 more 2026-09-29 7.1 High
A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted certificate that contains Uniform Resource Identifier (URI) or Service (SRV) Subject Alternative Names (SANs). This could cause the certificate validation process to incorrectly fall back to checking DNS hostnames against the Common Name (CN), potentially allowing the attacker to spoof legitimate services or intercept sensitive information.
CVE-2026-15588 1 Redhat 15 Cert Manager, Discovery, Enterprise Linux and 12 more 2026-09-29 5.3 Medium
A denial-of-service and resource exhaustion vulnerability exists within the `GDBus` component of GLib. The `gdbusauth` authentication mechanism fails to enforce proper length limitations on data lines read from a client. An unauthenticated local or remote attacker can exploit this lack of input validation by sending excessively long streams of data, causing the application to consume massive amounts of system memory and CPU, potentially leading to a crash or system hang.
CVE-2026-14164 3 Libarchive, Red Hat, Redhat 13 Libarchive, Enterprise Linux, Cert Manager and 10 more 2026-09-29 7.5 High
A double free issue has been identified in libarchive's RAR5 reader. During parsing of a specially crafted RAR5 archive, the filtered_buf pointer may remain stale after being freed during unpacking state reinitialization. Subsequent processing of another archive entry can trigger a second free of the same memory region, resulting in a double-free condition. Successful exploitation may cause applications using the vulnerable libarchive API to terminate unexpectedly, leading to a denial of service.
CVE-2026-13757 2 P11-kit Project, Redhat 10 P11-kit, Cert Manager, Discovery and 7 more 2026-09-29 6.2 Medium
A flaw was found in p11-kit. The RPC message attribute parsing functions p11_rpc_message_get_attribute() and p11_rpc_message_get_attribute_array_value() form a mutually-recursive call chain with no recursion depth limit when processing nested CKA_WRAP_TEMPLATE, CKA_UNWRAP_TEMPLATE, and CKA_DERIVE_TEMPLATE attributes. An unauthenticated attacker with local access to the p11-kit RPC Unix domain socket can send a specially crafted request with deeply nested template attributes, causing stack exhaustion and crashing the p11-kit server process and its dependent services.
CVE-2026-5260 2 Gnu, Redhat 15 Gnutls, Cert Manager, Discovery and 12 more 2026-09-29 8.2 High
A flaw was found in libgnutls. A remote attacker, by sending an extremely short premaster secret during an RSA key exchange to a server using an RSA key backed by a PKCS#11 token, could trigger a short heap overread. This memory corruption vulnerability could lead to information disclosure.
CVE-2026-5121 2 Libarchive, Redhat 18 Libarchive, Ai Inference Server, Cert Manager and 15 more 2026-09-29 7.5 High
A flaw was found in libarchive. On 32-bit systems, an integer overflow vulnerability exists in the zisofs block pointer allocation logic. A remote attacker can exploit this by providing a specially crafted ISO9660 image, which can lead to a heap buffer overflow. This could potentially allow for arbitrary code execution on the affected system.
CVE-2026-3833 2 Gnu, Redhat 16 Gnutls, Cert Manager, Discovery and 13 more 2026-09-29 6.5 Medium
A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive comparisons of `nameConstraints` labels, specifically for `dNSName` (DNS) or `rfc822Name` (email) constraints within `excludedSubtrees` or `permittedSubtrees`. A remote attacker can exploit this by crafting a leaf certificate with casing differences in the Subject Alternative Name (SAN), leading to a policy bypass where a certificate that should be rejected is instead accepted. This could result in unauthorized access or information disclosure.
CVE-2026-42010 2 Gnu, Redhat 16 Gnutls, Ai Inference Server, Cert Manager and 13 more 2026-09-29 7.1 High
A flaw was found in gnutls. Servers configured with RSA-PSK (Rivest–Shamir–Adleman – Pre-Shared Key) wrongfully matched usernames containing a NUL character with truncated usernames. A remote attacker could exploit this by sending a specially crafted username, leading to an authentication bypass. This vulnerability allows an attacker to gain unauthorized access by circumventing the authentication process.
CVE-2026-42009 2 Gnu, Redhat 27 Gnutls, Ai Inference Server, Cert Manager and 24 more 2026-09-29 7.5 High
A flaw was found in gnutls. A remote attacker could exploit an issue in the Datagram Transport Layer Security (DTLS) packet reordering logic. The comparator function, responsible for ordering DTLS packets by sequence numbers, did not correctly handle packets with duplicate sequence numbers. This could lead to unstable packet ordering or undefined behavior, resulting in a denial of service.
CVE-2026-33846 2 Gnu, Redhat 17 Gnutls, Ai Inference Server, Cert Manager and 14 more 2026-09-29 7.5 High
A heap buffer overflow vulnerability exists in the DTLS handshake fragment reassembly logic of GnuTLS. The issue arises in merge_handshake_packet() where incoming handshake fragments are matched and merged based solely on handshake type, without validating that the message_length field remains consistent across all fragments of the same logical message. An attacker can exploit this by sending crafted DTLS fragments with conflicting message_length values, causing the implementation to allocate a buffer based on a smaller initial fragment and subsequently write beyond its bounds using larger, inconsistent fragments. Because the merge operation does not enforce proper bounds checking against the allocated buffer size, this results in an out-of-bounds write on the heap. The vulnerability is remotely exploitable without authentication via the DTLS handshake path and can lead to application crashes or potential memory corruption.
CVE-2026-33845 2 Gnu, Redhat 17 Gnutls, Ai Inference Server, Cert Manager and 14 more 2026-09-29 7.5 High
A flaw in GnuTLS DTLS handshake parsing allows malformed fragments with zero length and non-zero offset, leading to an integer underflow during reassembly and resulting in an out-of-bounds read. This issue is remotely exploitable and may cause information disclosure or denial of service.
CVE-2026-4878 2 Libcap Project, Redhat 19 Libcap, Ai Inference Server, Cert Manager and 16 more 2026-09-29 6.7 Medium
A flaw was found in libcap. A local unprivileged user can exploit a Time-of-check-to-time-of-use (TOCTOU) race condition in the `cap_set_file()` function. This allows an attacker with write access to a parent directory to redirect file capability updates to an attacker-controlled file. By doing so, capabilities can be injected into or stripped from unintended executables, leading to privilege escalation.
