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"
