CVE-2024-48957

Heap-memory disclosure or crash via RAR audio filter

Published Oct 10, 2024 · Updated Aug 29, 2025

Out-of-bounds read in libarchive before 3.7.5 allows attackers to disclose heap memory or crash a process via a crafted RAR archive. The execute_filter_audio loop in archive_read_support_format_rar.c increments src without checking whether it reaches the destination block. Processing the archive is required; disclosure depends on how a consuming application exposes read data, while an invalid read can terminate its process.
