Security hole in ClamAV
The developers of ClamAV, an open source virus scanner, have released a new version 0.88.5 of the software to close unearthed security holes. Attackers could use manipulated CHM help files to crash previous versions of the scanner, thereby executing a denial of service attack on the service. A buffer overflow could occur in the heap through the function for rebuilding of executable PE files after unpacking – whether ill-intentioned individuals could use this to plant arbitrary program code was not revealed in the Changelog.
The current code is available for download at the project's page at Sourceforge. Linux distributors are also likely soon to deliver updated packages of the virus scanner.
