Gentoo Linux Security Advisory
Title: ClamAV: Multiple Vulnerabilities (GLSA 200610-10)
Severity: high
Exploitable: remote
Date: October 24, 2006
Bug(s): #151561
ID: 200610-10
Synopsis
ClamAV is vulnerable to a heap-based buffer overflow potentially allowing remote execution of arbitrary code and a Denial of Service.
Background
ClamAV is a GPL virus scanner.
Affected Packages
Package: app-antivirus/clamav
Vulnerable: < 0.88.5
Unaffected: >= 0.88.5
Architectures: All supported architectures
Description
Damian Put and an anonymous researcher reported a potential heap-based buffer overflow vulnerability in rebuildpe.c responsible for the rebuilding of an unpacked PE file, and a possible crash in chmunpack.c in the CHM unpacker.
Impact
By sending a malicious attachment to a mail server running ClamAV, or providing a malicious file to ClamAV through any other method, a remote attacker could cause a Denial of Service and potentially the execution of arbitrary code with the permissions of the user running ClamAV.
Workaround
There is no known workaround at this time.
Resolution
All ClamAV users should upgrade to the latest version: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=app-antivirus/clamav-0.88.5" |
