ClamAV < 0.103.9 / 1.0.x < 1.0.2 / 1.1.x < 1.1.1 DoS

high Nessus Plugin ID 180465


The remote device is missing a vendor-supplied security patch.


A vulnerability in the filesystem image parser for Hierarchical File System Plus (HFS+) of ClamAV could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to an incorrect check for completion when a file is decompressed, which may result in a loop condition that could cause the affected software to stop responding. An attacker could exploit this vulnerability by submitting a crafted HFS+ filesystem image to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to cause the ClamAV scanning process to stop responding, resulting in a DoS condition on the affected software and consuming available system resources. For a description of this vulnerability, see the ClamAV blog.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.


Upgrade to ClamAV 0.103.9, 1.0.2, 1.1.1 or later
