Description
This security update for ClamAV addresses multiple vulnerabilities including improper boundary checks, invalid memory frees, integer overflows and underflows, out-of-bounds reads/writes, path traversal, and thread-safety issues. These flaws affect various parsers such as ZIP, PESpin, GPT partition names, PDF hex strings, Mach-O files, XAR, and OneNote notebooks. The update also fixes issues related to NTFS alternate data stream handling on Windows and improves thread safety and resource management in the daemon and cryptographic components.
