Several remote vulnerabilities have been discovered in the ClamAV anti-virus toolkit, which may lead to denial of service and potentially to the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2006-1614     Damian Put discovered an integer overflow in the PE     header parser. This is only exploitable if the     ArchiveMaxFileSize option is disabled.

  - CVE-2006-1615     Format string vulnerabilities in the logging code have     been discovered, which might lead to the execution of     arbitrary code.

  - CVE-2006-1630     David Luyer discovered, that ClamAV can be tricked into     an invalid memory access in the cli_bitset_set()     function, which may lead to a denial of service.

The remote host is affected by the vulnerability described in GLSA-200604-06 (ClamAV: Multiple vulnerabilities)

    ClamAV contains format string vulnerabilities in the logging code     (CVE-2006-1615). Furthermore Damian Put discovered an integer overflow     in ClamAV's PE header parser (CVE-2006-1614) and David Luyer discovered     that ClamAV can be tricked into performing an invalid memory access     (CVE-2006-1630).
  Impact :

    By sending a malicious attachment to a mail server running ClamAV,     a remote attacker could cause a Denial of Service or the execution of     arbitrary code. Note that the overflow in the PE header parser is only     exploitable when the ArchiveMaxFileSize option is disabled.
  Workaround :

    There is no known workaround at this time.

Damian Put discovered an integer overflow in the PE header parser in ClamAV that could be exploited if the ArchiveMaxFileSize option was disabled (CVE-2006-1614).

Format strings in the logging code could possibly lead to the execution of arbitrary code (CVE-2006-1615).

David Luyer found that ClamAV could be tricked into an invalid memory access in the cli_bitset_set() function, which could lead to a Denial of Service (CVE-2006-1630).

This update provides ClamAV 0.88.1 which corrects this issue and also fixes some other bugs.

The remote host is running Apple Mac OS X, but lacks Security Update 2006-003.

Secunia reports :

Some vulnerabilities have been reported in ClamAV, which potentially can be exploited by malicious people to cause a DoS (Denial of Service) and compromise a vulnerable system.

An unspecified integer overflow error exists in the PE header parser in 'libclamav/pe.c'. Successful exploitation requires that the ArchiveMaxFileSize option is disabled.

Some format string errors in the logging handling in 'shared/output.c' may be exploited to execute arbitrary code.

An out-of-bounds memory access error in the 'cli_bitset_test()' function in 'ibclamav/others.c' may be exploited to cause a crash.

The remote host is using a version of curl (or libcurl) that is vulnerable to a remote buffer overflows. To exploit, an attacker would have to set up a rogue web server and entice a curl user into browsing to the malicious server.  Upon successful exploitation, the attacker would be able to execute arbitrary commands with the rights of the web server.

The remote host is running ClamAV, an antivirus application. There are a number of flaws that affect this version of ClamAV, and the vendor recommends upgrading to version 0.88.1 or higher. 

The remote host is using a version of curl (or libcurl) that is vulnerable to a remote buffer overflows. To exploit, an attacker would have to set up a rogue web server that would reply with a malicious NTLM authentication request.  Upon successful exploitation, the attacker would be able to execute arbitrary commands with the rights of the web server.

The remote host is using a version of wget that contains a flaw in the way that it handles NTLM authentication data.  Specifically, a rogue website that returns malformed data during an NTLM authentication session will be able to execute arbitrary code on the local client machine. 

The remote Mac OS X host is running a version of Quicktime prior to 7.1.  The remote version of Quicktime is vulnerable to various integer and buffer overflows involving specially-crafted image and media files.  An attacker may be able to leverage these issues to execute arbitrary code on the remote host by sending a malformed file to a victim and having it opened using QuickTime player.
