In the Linux kernel, the following vulnerability has been resolved: bfs: Reconstructing the file type when loading from disk syzbot reports that the SIFMT bits of the inode-imode field can become invalid when: 1. The 32-bit “mode” field loaded from disk is corrupted; 2. The 32-bit “attributes”...

Astra Linux – Vulnerability in lxml

A XSS vulnerability was discovered in the python-lxml’s clean module versions prior to 4.6.3. When the “safe attrsonly” and “forms” arguments are disabled, the Cleaner class does not remove the “formaction” attribute, allowing JavaScript to bypass the sanitizer. A remote attacker could exploit th...
