Severity: High Title: ClamAV: Heap buffer overflow Date: August 08, 2006 Bugs: #143093 ID: 200608-13

Synopsis ========
ClamAV is vulnerable to a heap-based buffer overflow resulting in a Denial of Service and potentially remote execution of arbitrary code.
Background ==========
ClamAV is a GPL virus scanner.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-antivirus/clamav < 0.88.4 >= 0.88.4
Description ===========
Damian Put has discovered a boundary error in the pefromupx() function used by the UPX extraction module, which unpacks PE Windows executable files. Both the "clamscan" command-line utility and the "clamd" daemon are affected.
Impact ======
By sending a malicious attachment to a mail server running ClamAV, a remote attacker can 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:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-antivirus/clamav-0.88.4"
References ==========
