Clam Anti-virus Clamav .

The OLE2 unpacker in clamd in Clam AntiVirus (ClamAV) 0.87-1 allows remote attackers to cause a denial of service (segmentation fault) via a DOC file with an invalid property tree, which triggers an infinite recursion in the ole2_walk_property_tree function.

Integer overflow in ClamAV 0.88.1 and 0.88.4, and other versions before 0.88.5, allows remote attackers to cause a denial of service (scanning service crash) and execute arbitrary code via a crafted Portable Executable (PE) file that leads to a heap-based buffer overflow when less memory is allocated than expected.

Heap-based buffer overflow in libclamav/upx.c in Clam Antivirus (ClamAV) before 0.88 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted UPX files.

Unspecified vulnerability in ClamAV before 0.88.5 allows remote attackers to cause a denial of service (scanning service crash) via a crafted Compressed HTML Help (CHM) file that causes ClamAV to "read an invalid memory location."

Clam AntiVirus (ClamAV) 0.88 and earlier allows remote attackers to cause a denial of service (crash) via a malformed base64-encoded MIME attachment that triggers a null pointer dereference.
