https://notcve.org/view.php?id=CVE-2025-7425
10 Jul 2025 — A flaw was found in libxslt where the attribute type, atype, flags are modified in a way that corrupts internal memory management. When XSLT functions, such as the key() process, result in tree fragments, this corruption prevents the proper cleanup of ID attributes. As a result, the system may access freed memory, causing crashes or enabling attackers to trigger heap corruption. An update for libxml2 is now available for Red Hat Enterprise Linux 8.6 Advanced Mission Critical Update Support, Red Hat Enterpri... • https://access.redhat.com/security/cve/CVE-2025-7425 • CWE-416: Use After Free •

CVE-2025-32988 – Gnutls: vulnerability in gnutls othername san export
https://notcve.org/view.php?id=CVE-2025-32988
09 Jul 2025 — 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 ... • https://access.redhat.com/security/cve/CVE-2025-32988 • CWE-415: Double Free •

CVE-2025-4878 – Libssh: use of uninitialized variable in privatekey_from_file()
https://notcve.org/view.php?id=CVE-2025-4878
04 Jul 2025 — A vulnerability was found in libssh, where an uninitialized variable exists under certain conditions in the privatekey_from_file() function. This flaw can be triggered if the file specified by the filename doesn't exist and may lead to possible signing failures or heap corruption. Ronald Crane discovered that libssh incorrectly handled certain base64 conversions. An attacker could use this issue to cause libssh to crash, resulting in a denial of service, or possibly execute arbitrary code. Ronald Crane disc... • https://access.redhat.com/security/cve/CVE-2025-4878 • CWE-416: Use After Free •

CVE-2025-4877 – Libssh: write beyond bounds in binary to base64 conversion functions
https://notcve.org/view.php?id=CVE-2025-4877
04 Jul 2025 — There's a vulnerability in the libssh package where when a libssh consumer passes in an unexpectedly large input buffer to ssh_get_fingerprint_hash() function. In such cases the bin_to_base64() function can experience an integer overflow leading to a memory under allocation, when that happens it's possible that the program perform out of bounds write leading to a heap corruption. This issue affects only 32-bits builds of libssh. There's a vulnerability in the libssh package where when a libssh consumer pass... • https://access.redhat.com/security/cve/CVE-2025-4877 • CWE-787: Out-of-bounds Write •

CVE-2025-32462 – Sudo 1.9.17 Host Option - Elevation of Privilege
https://notcve.org/view.php?id=CVE-2025-32462
30 Jun 2025 — Sudo before 1.9.17p1, when used with a sudoers file that specifies a host that is neither the current host nor ALL, allows listed users to execute commands on unintended machines. A privilege escalation vulnerability was found in Sudo. In certain configurations, unauthorized users can gain elevated system privileges via the Sudo host option (`-h` or `--host`). When using the default sudo security policy plugin (sudoers), the host option is intended to be used in conjunction with the list option (`-l` or `--... • https://packetstorm.news/files/id/206211 • CWE-863: Incorrect Authorization •

CVE-2025-32463 – Sudo chroot 1.9.17 - Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2025-32463
30 Jun 2025 — Sudo before 1.9.17p1 allows local users to obtain root access because /etc/nsswitch.conf from a user-controlled directory is used with the --chroot option. A flaw was found in Sudo. This flaw allows a local attacker to escalate their privileges by tricking Sudo into loading an arbitrary shared library using the user-specified root directory via the `-R` (`--chroot`) option. An attacker can run arbitrary commands as root on systems that support `/etc/nsswitch.conf`. Rich Mirch discovered that Sudo incorrectl... • https://packetstorm.news/files/id/206210 • CWE-427: Uncontrolled Search Path Element CWE-829: Inclusion of Functionality from Untrusted Control Sphere •

CVE-2025-5318 – Libssh: out-of-bounds read in sftp_handle()
https://notcve.org/view.php?id=CVE-2025-5318
24 Jun 2025 — A flaw was found in the libssh library. An out-of-bounds read can be triggered in the sftp_handle function due to an incorrect comparison check that permits the function to access memory beyond the valid handle list and to return an invalid pointer, which is used in further processing. This vulnerability allows an authenticated remote attacker to potentially read unintended memory regions, exposing sensitive information or affect service behavior. Ronald Crane discovered that libssh incorrectly handled cert... • https://access.redhat.com/security/cve/CVE-2025-5318 • CWE-125: Out-of-bounds Read •

CVE-2025-6018 – Pam-config: lpe from unprivileged to allow_active in pam
https://notcve.org/view.php?id=CVE-2025-6018
18 Jun 2025 — A Local Privilege Escalation (LPE) vulnerability has been discovered in pam-config within Linux Pluggable Authentication Modules (PAM). This flaw allows an unprivileged local attacker (for example, a user logged in via SSH) to obtain the elevated privileges normally reserved for a physically present, "allow_active" user. The highest risk is that the attacker can then perform all allow_active yes Polkit actions, which are typically restricted to console users, potentially gaining unauthorized control over sy... • https://packetstorm.news/files/id/207433 • CWE-863: Incorrect Authorization •

CVE-2025-49178 – Xorg-x11-server-xwayland: xorg-x11-server: tigervnc: unprocessed client request due to bytes to ignore
https://notcve.org/view.php?id=CVE-2025-49178
17 Jun 2025 — A flaw was found in the X server's request handling. Non-zero 'bytes to ignore' in a client's request can cause the server to skip processing another client's request, potentially leading to a denial of service. This update for xorg-x11-server fixes the following issues. Out-of-bounds access in X Rendering extension (Animated cursors). Integer overflow in Big Requests Extension. • https://access.redhat.com/security/cve/CVE-2025-49178 • CWE-667: Improper Locking •

CVE-2025-49175 – Xorg-x11-server-xwayland: xorg-x11-server: tigervnc: out-of-bounds read in x rendering extension animated cursors
https://notcve.org/view.php?id=CVE-2025-49175
17 Jun 2025 — A flaw was found in the X Rendering extension's handling of animated cursors. If a client provides no cursors, the server assumes at least one is present, leading to an out-of-bounds read and potential crash. USN-7573-1 fixed several vulnerabilities in X.Org. This update provides the corresponding update for Ubuntu 16.04 LTS, Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. Nils Emmerich discovered that the X.Org X Server incorrectly handled certain memory operations. • https://access.redhat.com/security/cve/CVE-2025-49175 • CWE-125: Out-of-bounds Read •
