|Gentoo Linux Security Advisory
Title: ClamAV: Heap buffer overflow (GLSA 200608-13)
Date: August 08, 2006
ClamAV is vulnerable to a heap-based buffer overflow resulting in a Denial
of Service and potentially remote execution of arbitrary code.
ClamAV is a GPL virus scanner.
Vulnerable: < 0.88.4
Unaffected: >= 0.88.4
Architectures: All supported architectures
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
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
There is no known workaround at this time.
All ClamAV users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=app-antivirus/clamav-0.88.4"
