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.
The CLI_ISCONTAINED macro in libclamav/others.h in ClamAV before 0.95.1 allows remote attackers to cause a denial of service (application crash) via a malformed file with UPack encoding.
Stack-based buffer overflow in the cli_url_canon function in libclamav/phishcheck.c in ClamAV before 0.95.1 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted URL.
libclamav/pe.c in ClamAV before 0.95 allows remote attackers to cause a denial of service (crash) via a crafted EXE file that triggers a divide-by-zero error.
libclamav/untar.c in ClamAV before 0.95 allows remote attackers to cause a denial of service (infinite loop) via a crafted TAR file that causes (1) clamd and (2) clamscan to hang.
libclamav in ClamAV before 0.94 allows attackers to cause a denial of service (NULL pointer dereference and application crash) via vectors related to an out-of-memory condition.
Multiple memory leaks in freshclam/manager.c in ClamAV before 0.94 might allow attackers to cause a denial of service (memory consumption) via unspecified vectors related to "error handling logic".
