| CVE-2025-32990 | 2 Gnu, Redhat | 10 Gnutls, Ceph Storage, Discovery and 7 more | 2026-04-14 | 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 | 2026-04-14 | 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 | 2026-04-14 | 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-2026-5704 | 1 Redhat | 2 Enterprise Linux, Hummingbird | 2026-04-12 | 5 Medium |
| A flaw was found in tar. A remote attacker could exploit this vulnerability by crafting a malicious archive, leading to hidden file injection with fully attacker-controlled content. This bypasses pre-extraction inspection mechanisms, potentially allowing an attacker to introduce malicious files onto a system without detection. | ||||
| CVE-2026-4105 | 1 Redhat | 4 Enterprise Linux, Hummingbird, Openshift and 1 more | 2026-04-10 | 6.7 Medium |
| A flaw was found in systemd. The systemd-machined service contains an Improper Access Control vulnerability due to insufficient validation of the class parameter in the RegisterMachine D-Bus (Desktop Bus) method. A local unprivileged user can exploit this by attempting to register a machine with a specific class value, which may leave behind a usable, attacker-controlled machine object. This allows the attacker to invoke methods on the privileged object, leading to the execution of arbitrary commands with root privileges on the host system. | ||||
| CVE-2026-4426 | 2 Libarchive, Redhat | 5 Libarchive, Enterprise Linux, Hummingbird and 2 more | 2026-04-10 | 6.5 Medium |
| A flaw was found in libarchive. An Undefined Behavior vulnerability exists in the zisofs decompression logic, caused by improper validation of a field (`pz_log2_bs`) read from ISO9660 Rock Ridge extensions. A remote attacker can exploit this by supplying a specially crafted ISO file. This can lead to incorrect memory allocation and potential application crashes, resulting in a denial-of-service (DoS) condition. | ||||
| CVE-2026-4647 | 2 Gnu, Redhat | 5 Binutils, Enterprise Linux, Hummingbird and 2 more | 2026-04-10 | 6.1 Medium |
| A flaw was found in the GNU Binutils BFD library, a widely used component for handling binary files such as object files and executables. The issue occurs when processing specially crafted XCOFF object files, where a relocation type value is not properly validated before being used. This can cause the program to read memory outside of intended bounds. As a result, affected tools may crash or expose unintended memory contents, leading to denial-of-service or limited information disclosure risks. | ||||
| CVE-2026-5745 | 2 Libarchive, Redhat | 5 Libarchive, Enterprise Linux, Hummingbird and 2 more | 2026-04-10 | 5.5 Medium |
| A flaw was found in libarchive. A NULL pointer dereference vulnerability exists in the ACL parsing logic, specifically within the archive_acl_from_text_nl() function. When processing a malformed ACL string (such as a bare "d" or "default" tag without subsequent fields), the function fails to perform adequate validation before advancing the pointer. An attacker can exploit this by providing a maliciously crafted archive, causing an application utilizing the libarchive API (such as bsdtar) to crash, resulting in a Denial of Service (DoS). | ||||
| CVE-2025-14821 | 2 Libssh, Redhat | 4 Libssh, Enterprise Linux, Hummingbird and 1 more | 2026-04-08 | 7.8 High |
| A flaw was found in libssh. This vulnerability allows local man-in-the-middle attacks, security downgrades of SSH (Secure Shell) connections, and manipulation of trusted host information, posing a significant risk to the confidentiality, integrity, and availability of SSH communications via an insecure default configuration on Windows systems where the library automatically loads configuration files from the C:\etc directory, which can be created and modified by unprivileged local users. | ||||
