Buffer overflow in the find_stream_bounds function in pdf.c in libclamav in ClamAV before 0.96.3 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted PDF document. NOTE: some of these details are obtained from third party information.

The cli_pdf function in libclamav/pdf.c in ClamAV before 0.96.1 allows remote attackers to cause a denial of service (crash) via a malformed PDF file, related to an inconsistency in the calculated stream length and the real stream length.
