| CVE-2026-4775 | 3 Debian, Libtiff, Redhat | 13 Debian Linux, Libtiff, Ai Inference Server and 10 more | 2026-06-30 | 7.8 High |
| A flaw was found in the libtiff library. A remote attacker could exploit a signed integer overflow vulnerability in the putcontig8bitYCbCr44tile function by providing a specially crafted TIFF file. This flaw can lead to an out-of-bounds heap write due to incorrect memory pointer calculations, potentially causing a denial of service (application crash) or arbitrary code execution. | ||||
| CVE-2026-13595 | 2 Linux, Redhat | 6 Util-linux, Enterprise Linux, Hardened Images and 3 more | 2026-06-30 | 6.8 Medium |
| A flaw was found in the libblkid library of util-linux. During nested partition probing, the BSD, Minix, Solaris x86, and UnixWare partition probers cache a raw pointer to a parent partition entry in a dynamically allocated array. When subsequent partition additions cause the array to be reallocated, this pointer becomes stale, leading to a heap use-after-free read. An attacker who can present a crafted block device image (for example, via USB insertion or a loop-mounted disk image) can trigger this flaw without user interaction, as libblkid is invoked automatically by udev/udisks as root on block-device hot-plug events. This could lead to limited information disclosure or denial of service. | ||||
| CVE-2026-42015 | 1 Redhat | 13 Discovery, Enterprise Linux, Enterprise Linux Eus and 10 more | 2026-06-30 | 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 | 14 Gnutls, Discovery, Enterprise Linux and 11 more | 2026-06-30 | 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 | 14 Gnutls, Discovery, Enterprise Linux and 11 more | 2026-06-30 | 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-2026-42012 | 2 Gnu, Redhat | 14 Gnutls, Discovery, Enterprise Linux and 11 more | 2026-06-30 | 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-2026-42011 | 1 Redhat | 13 Discovery, Enterprise Linux, Enterprise Linux Eus and 10 more | 2026-06-30 | 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-2026-5260 | 2 Gnu, Redhat | 14 Gnutls, Discovery, Enterprise Linux and 11 more | 2026-06-30 | 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-2026-3833 | 2 Gnu, Redhat | 14 Gnutls, Discovery, Enterprise Linux and 11 more | 2026-06-30 | 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-2024-12133 | 1 Redhat | 8 Discovery, Enterprise Linux, Openshift and 5 more | 2026-06-30 | 5.3 Medium |
| A flaw in libtasn1 causes inefficient handling of specific certificate data. When processing a large number of elements in a certificate, libtasn1 takes much longer than expected, which can slow down or even crash the system. This flaw allows an attacker to send a specially crafted certificate, causing a denial of service attack. | ||||
| CVE-2025-9901 | 1 Redhat | 1 Enterprise Linux | 2026-06-30 | 5.9 Medium |
| A flaw was found in libsoup’s caching mechanism, SoupCache, where the HTTP Vary header is ignored when evaluating cached responses. This header ensures that responses vary appropriately based on request headers such as language or authentication. Without this check, cached content can be incorrectly reused across different requests, potentially exposing sensitive user information. While the issue is unlikely to affect everyday desktop use, it could result in confidentiality breaches in proxy or multi-user environments. | ||||
| CVE-2025-8114 | 2 Libssh, Redhat | 3 Libssh, Enterprise Linux, Openshift | 2026-06-30 | 4.7 Medium |
| A flaw was found in libssh, a library that implements the SSH protocol. When calculating the session ID during the key exchange (KEX) process, an allocation failure in cryptographic functions may lead to a NULL pointer dereference. This issue can cause the client or server to crash. | ||||
| CVE-2025-7519 | 1 Redhat | 3 Enterprise Linux, Openshift, Openshift Container Platform | 2026-06-30 | 6.7 Medium |
| A flaw was found in polkit. When processing an XML policy with 32 or more nested elements in depth, an out-of-bounds write can be triggered. This issue can lead to a crash or other unexpected behavior, and arbitrary code execution is not discarded. To exploit this flaw, a high-privilege account is needed as it's required to place the malicious policy file properly. | ||||
| CVE-2025-7345 | 1 Redhat | 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more | 2026-06-30 | 7.5 High |
| A flaw exists in gdk‑pixbuf within the gdk_pixbuf__jpeg_image_load_increment function (io-jpeg.c) and in glib’s g_base64_encode_step (glib/gbase64.c). When processing maliciously crafted JPEG images, a heap buffer overflow can occur during Base64 encoding, allowing out-of-bounds reads from heap memory, potentially causing application crashes or arbitrary code execution. | ||||
| CVE-2025-6395 | 1 Redhat | 7 Ceph Storage, Discovery, Enterprise Linux and 4 more | 2026-06-30 | 6.5 Medium |
| A NULL pointer dereference flaw was found in the GnuTLS software in _gnutls_figure_common_ciphersuite(). | ||||
| CVE-2025-32990 | 2 Gnu, Redhat | 10 Gnutls, Ceph Storage, Discovery and 7 more | 2026-06-30 | 6.5 Medium |
| A heap-buffer-overflow (off-by-one) flaw was found in the GnuTLS software in the template parsing logic within the certtool utility. When it reads certain settings from a template file, it allows an attacker to cause an out-of-bounds (OOB) NULL pointer write, resulting in memory corruption and a denial-of-service (DoS) that could potentially crash the system. | ||||
| CVE-2025-32989 | 2 Gnu, Redhat | 10 Gnutls, Ceph Storage, Discovery and 7 more | 2026-06-30 | 5.3 Medium |
| A heap-buffer-overread vulnerability was found in GnuTLS in how it handles the Certificate Transparency (CT) Signed Certificate Timestamp (SCT) extension during X.509 certificate parsing. This flaw allows a malicious user to create a certificate containing a malformed SCT extension (OID 1.3.6.1.4.1.11129.2.4.2) that contains sensitive data. This issue leads to the exposure of confidential information when GnuTLS verifies certificates from certain websites when the certificate (SCT) is not checked correctly. | ||||
| CVE-2025-32988 | 2 Gnu, Redhat | 10 Gnutls, Ceph Storage, Discovery and 7 more | 2026-06-30 | 6.5 Medium |
| A flaw was found in GnuTLS. A double-free vulnerability exists in GnuTLS due to incorrect ownership handling in the export logic of Subject Alternative Name (SAN) entries containing an otherName. If the type-id OID is invalid or malformed, GnuTLS will call asn1_delete_structure() on an ASN.1 node it does not own, leading to a double-free condition when the parent function or caller later attempts to free the same structure. This vulnerability can be triggered using only public GnuTLS APIs and may result in denial of service or memory corruption, depending on allocator behavior. | ||||
| CVE-2025-32914 | 1 Redhat | 6 Enterprise Linux, Rhel Aus, Rhel E4s and 3 more | 2026-06-30 | 7.4 High |
| A flaw was found in libsoup, where the soup_multipart_new_from_message() function is vulnerable to an out-of-bounds read. This flaw allows a malicious HTTP client to induce the libsoup server to read out of bounds. | ||||
| CVE-2025-32912 | 1 Redhat | 1 Enterprise Linux | 2026-06-30 | 6.5 Medium |
| A flaw was found in libsoup, where SoupAuthDigest is vulnerable to a NULL pointer dereference. The HTTP server may cause the libsoup client to crash. | ||||
