Detail

A number of potential remote DOS vulnerabilities have been identified in ClamAV. In addition to the four issues identified by CVE ID above, there are fixes for issues in libclamav/cvd.c and libclamav/message.c. Together, these issues could allow a carefully crafted message to crash a ClamAV scanner or exhaust various resources on the machine running the scanner.

For the stable distribution (sarge), these problems have been fixed in version 0.84-2.sarge.1.

We recommend that you upgrade your clamav package.

Open Source Vulnerability Database (OSVDB)

Id Description
17646 Clam AntiVirus MS-Expand File Handling DoS

ClamAV contains a flaw that may allow a remote denial of service. The issue is triggered by a file descriptor leak in cli_msexpand() function, located in libclamav/scanners.c, which consumes all available file descriptors and/or memory on the target system. A remote attacker sends approximately 1,000 specially crafted archive files, either by email attachment or directly to a current HTTP session, resulting in a loss of availability of the anti-virus system.
17645 Clam AntiVirus Zero Length Cabinet File ENSURE_BITS() Macro DoS

ClamAV contains a flaw that may allow a remote denial of service. The issue is triggered when the ENSURE_BITS() function in the libclamav/mspack/mszipd.c fails to properly validate user supplied input. A remote attacker could send a specially crafted CAB file with a cffile_FolderOffset set to 0xff to cause the program to enter an infinite loop, resulting in a loss of availability of the anti-virus system.
17562 ClamAV clamav-milter Remote Connection Hold DoS

17544 Clam AntiVirus Unspecified Quantum Decompressor DoS

ClamAV contains a flaw that may allow a remote denial of service. The issue is triggered when ClamAV is scanning a Quantum compressed archive with a window size less than 32KB, and will result in loss of availability for the service.
