Description
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. Attackers can supply a crafted compressed XBIN file ending in a control byte such as 0x7F to read past the input buffer, crashing applications that render untrusted XBIN art.
