High
| Vector | AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
ClamAV versions 0.103.5 and earlier
ClamAV versions 0.104.0 through 0.104.2
Description
A vulnerability in the CHM file parser of Clam AntiVirus could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected device. The issue is related to errors in resource management during CHM file parsing, which may lead to a denial of service condition. Exploitation of the vulnerability may allow a remote attacker to consume all available system resources, causing a denial of service.
Recommendations
For ClamAV versions 0.103.5 and earlier, update to a version later than 0.103.5.
For ClamAV versions 0.104.0 through 0.104.2, update to a version later than 0.104.2.
As a temporary workaround, consider disabling the CHM file parser until a patch is available.
Restrict access to the CHM file parser to minimize the risk of exploitation.
Fix
