Description Vladimir Vasilev 2026-10-16 17:35:21 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

libsidplayfp through 3.1.1 contains a heap out-of-bounds read vulnerability that allows attackers to crash applications by supplying a PSID/RSID file with an unchecked data offset. Attackers can set the header data offset beyond the file size, wrapping the length calculation so resolveAddrs() reads up to 64 KiB past the heap buffer.
