The version of Symantec Protection Engine (SPE) installed on the remote Linux host is 7.0.x prior to 7.0.5 hotfix 02, 7.5.x prior to 7.5.5 hotifx 01, or 7.8.x prior to 7.8.0 hotifx 03. It is, therefore, affected by multiple denial of service vulnerabilities :
A denial of service vulnerability exists in the decomposer engine due to an out-of-bounds read error that occurs when decompressing RAR archives. An unauthenticated, remote attacker can exploit this, via a specially crafted RAR file, to crash the application.
(CVE-2016-5309)
