JLSEC-2025-238 Libarchive through 3.6.2 can cause directories to have world-writable permissions

Libarchive through 3.6.2 can cause directories to have world-writable permissions. The umask call inside archivewritediskposix.c changes the umask of the whole process for a very short period of time; a race condition with another thread can lead to a permanent umask 0 setting. Such a race...

JLSEC-2025-246 A vulnerability has been identified in the libarchive library

A vulnerability has been identified in the libarchive library. This flaw can lead to a heap buffer over-read due to the size of a filter block potentially exceeding the Lempel-Ziv-Storer-Schieber LZSS window. This means the library may attempt to read beyond the allocated memory buffer, which can...

JLSEC-2025-249 A vulnerability has been identified in the libarchive library

A vulnerability has been identified in the libarchive library. This flaw can be triggered when file streams are piped into bsdtar, potentially allowing for reading past the end of the file. This out-of-bounds read can lead to unintended consequences, including unpredictable program behavior, memo...
