Summary

Ansilove libansilove through 1.4.2 contains an out-of-bounds read in ansilove_xbin() (CWE-125). The function does not check bounds for compressed run-length records, so reads can go past the input buffer. A local user must open a crafted compressed XBIN file, which can crash applications that render untrusted XBIN art. A public exploit is linked in the references.

Description from the CNA

Ansilove libansilove through 1.4.2 contains an out-of-bounds read vulnerability in ansilove_xbin() in src/loaders/xbin.c that lacks bounds checks for compressed run-length records.
