Directory Traversal

Python Liquid is vulnerable to Directory Traversal. The vulnerability is due to insufficient validation of absolute file paths in the FileSystemLoader and CachingFileSystemLoader, which allows a malicious template author to load and render arbitrary files outside the configured search paths using...

USN-8279-2: Linux kernel (GCP) vulnerabilities

It was discovered that the Linux kernel algifaead module did not properly handle in-place cryptographic operations. This flaw is known as Copy Fail. A local attacker could use this to escalate privileges, or possibly escape a container. CVE-2026-31431 Several security issues were discovered in th...

CVE-2026-45252 Heap overflow in FUSE_LISTXATTR

When a fusefs file system implements extended attributes, the kernel may send a FUSELISTXATTR message to the userspace daemon to retrieve the list of extended attributes for a given file. The FUSE protocol requires the daemon to return a packed list of NUL-terminated strings. The fusefs kernel...

CVE-2026-45252

CVE-2026-45252 : In fusefs, when extended attributes are queried via FUSE_LISTXATTR, the kernel may call strlen() on a daemon-provided buffer without ensuring the list is fully NUL-terminated. If the list is not NUL-terminated, the fusefs kernel module may read past the end of a heap buffer and p...

FreeBSD : FreeBSD -- Heap overflow in FUSE_LISTXATTR (3cc34467-54b6-11f1-8d7a-bc241121aa0a)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 3cc34467-54b6-11f1-8d7a-bc241121aa0a advisory. When a fusefs file system implements extended attributes, the kernel may send a FUSELISTXATTR message t...
