Summary
The decomposer engine in Symantec Endpoint Protection (SEP) 11.0, Symantec Endpoint Protection Small Business Edition 12.0, Symantec AntiVirus Corporate Edition (SAVCE) 10.x, and Symantec Scan Engine (SSE) before 5.2.8 does not properly perform bounds checks of the contents of CAB archives, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted file.
Exploit prediction
6.04% chance of exploitation in the next 30 days, higher than 93% of all scored CVEs (FIRST EPSS, 2026-11-09).
