CVE-2026-48103 GHSL-2026-119 7-Zip WIM SecurityId OOB read

7-Zip is a file archiver with a high compression ratio. Versions 9.34 through 26.00 contain an off-by-one heap out-of-bounds read in the WIM Windows Imaging archive handler's security descriptor lookup. In CHandler::GetSecurity CPP/7zip/Archive/Wim/WimHandler.cpp, the per-image SecurOffsets table...

CVE-2026-48103

7-Zip (versions 9.34–26.00) contains an off-by-one heap out-of-bounds read in the WIM archive handler’s security descriptor lookup (WimHandler.cpp). The per-image SecurOffsets table uses numEntries+1 offsets; a securityId equal to numEntries is allowed and then reads SecurOffsets[securityId+1], r...
