SynopsisThe remote antivirus service is affected by multiple vulnerabilities.
DescriptionAccording to its version, the clamd antivirus daemon on the remote host is earlier than 0.96.3. Such versions are reportedly affected by multiple vulnerabilities :
- There is a failure to properly parse a specially crafted PDF file because of insufficient bounds-checks on PDF files in the 'find_stream_bounds()' function of the libclamav 'pdf.c' source file. (Bug 2226)
- An integer overflow can be triggered in the 'BZ2_decompress' function when parsing specially crafted BZ2 files, which could cause the server to crash or potentially allow execution of arbitrary code. (Bugs 2230, 2231)
SolutionUpgrade to ClamAV 0.96.3 or later.
