The FSG unpacker (fsg.c) in Clam AntiVirus (ClamAV) 0.80 through 0.87 allows remote attackers to cause "memory corruption" and execute arbitrary code via a crafted FSG 1.33 file.

The cabd_find function in cabd.c of the libmspack library (mspack) for Clam AntiVirus (ClamAV) before 0.87.1 allows remote attackers to cause a denial of service (infinite loop) via a crafted CAB file that causes cabd_find to be called with a zero length.

The tnef_attachment function in tnef.c for Clam AntiVirus (ClamAV) before 0.87.1 allows remote attackers to cause a denial of service (infinite loop and memory exhaustion) via a crafted value in a CAB file that causes ClamAV to repeatedly scan the same block.

Buffer overflow in libclamav/upx.c in Clam AntiVirus (ClamAV) before 0.87 allows remote attackers to execute arbitrary code via a crafted UPX packed executable.

libclamav/fsg.c in Clam AntiVirus (ClamAV) before 0.87 allows remote attackers to cause a denial of service (infinite loop) via a crafted FSG packed executable.

ClamAV 0.80 and earlier allows remote attackers to bypass virus scanning via a base64 encoded image in a data: (RFC 2397) URL.

ClamAV 0.80 and earlier allows remote attackers to cause a denial of service (clamd daemon crash) via a ZIP file with malformed headers.
