10.0

CVSS v3.1

Official Description

Multiple buffer overflows in Sophos Anti-Virus scanning engine before 2.40 allow remote attackers to execute arbitrary code via (1) a SIT archive with a long filename that is not null-terminated, which triggers a heap-based overflow in veex.dll due to improper length calculation, and (2) a CPIO archive, with a long filename that is not null-terminated, which triggers a stack-based overflow in veex.dll.

Technical Analysis

CVE-2006-6335 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
