- Summary
- Cups: openprinting cups: heap out-of-bounds read in cupsutf32toutf8() via missing source-length bound
- Details
-
The cupsUTF32ToUTF8() function in CUPS's cups/transcode.c lacks a source-length bound and can read past the end of the source buffer, resulting in a heap out-of-bounds read. This is reachable via SNMP supply-description parsing in backend/snmp-supplies.c with attacker-controlled content.
