ClamAV contains several vulnerabilities leading to a Denial of Service.
|Package||app-antivirus/clamav on all architectures|
|Affected versions||< 0.90.3|
|Unaffected versions||>= 0.90.3|
ClamAV is a GPL virus scanner.
Several vulnerabilities were discovered in ClamAV by various researchers:
A remote attacker could send a specially crafted file to the scanner, possibly triggering one of the vulnerabilities. The two buffer overflows are reported to only cause Denial of Service. This would lead to a Denial of Service by CPU consumption or a crash of the scanner. The insecure temporary file creation vulnerability could be used by a local user to access sensitive data.
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-0.90.3"
