ClamAV < 0.98.6 Multiple Vulnerabilities

High Nessus Plugin ID 81147

Synopsis

The antivirus service running on the remote host is affected by multiple vulnerabilities.

Description

According to its version, the ClamAV clamd antivirus daemon on the remote host is prior to 0.98.6. It is, therefore, 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 MEW packer 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.
