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 •

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 •

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.
