ClamAV < 0.98.6 Multiple Vulnerabilities

high Nessus Network Monitor Plugin ID 8826
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote host is running an anti-virus application that is affected by multiple vulnerabilities.

Description

Versions of ClamAV earlier than 0.98.6 are potentially affected by the following vulnerabilities :

- An out-of-bounds access flaw exists in the 'unupack()' function that is triggered when parsing a specially crafted Upack packer file. A remote attacker can exploit this to crash the application, resulting in a denial of service condition. (CVE-2014-9328)
- An out-of-bounds access flaw exists that is triggered when parsing maliciously crafted Yoda Crypter and MEWpacker files. A remote attacker can exploit this to crash the application, resulting in a denial of service condition. (CVE-2015-1461)
- An out-of-bounds access flaw exists that is triggered when parsing a specially crafted UPX packer file. A remote attacker can exploit this to crash the application, resulting in a denial of service condition. (CVE-2015-1462)
- A signedness flaw exists in the 'petite_inflate2x_1to9()' function in 'libclamav/petite.c' that allows a remote attacker with a specially crafted petite packer file to cause a denial of service. (CVE-2015-1463)
- An integer overflow condition exists in 'upx.c' due to improper validation of user-supplied input when scanning EXE files. An attacker can exploit this to cause a heap-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code.

Solution

Upgrade to ClamAV 0.98.6 or later.
