Description:
Two vulnerabilities have been reported in clamav, which can be exploited by malicious people to cause a DoS (Denial of Service).
1) An error in the "ENSURE_BITS()" macro when validating the header of a CAB file can lead to an infinite loop when the "cffile_cffile_FolderOffset" header value is set to "0xff".
Successful exploitation causes clamav to exhaust all system resources.
2) An error in the "cli_scanszdd()" function causes two file descriptors to be leaked whenever an attempt to decompress a file using the "cli_msexpand()" function fails. This causes clamav to exhaust all file descriptors after scanning approximately 1000 malformed files.
