Description

According 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)
