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.

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.

Off-by-one error in the get_unicode_name function (libclamav/vba_extract.c) in Clam Anti-Virus (ClamAV) before 0.94.1 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted VBA project file, which triggers a heap-based buffer overflow.

libclamav/petite.c in ClamAV before 0.93.1 allows remote attackers to cause a denial of service via a crafted Petite file that triggers an out-of-bounds read.

libclamunrar in ClamAV before 0.93 allows remote attackers to cause a denial of service (crash) via crafted RAR files that trigger "memory problems," as demonstrated by the PROTOS GENOME test suite for Archive Formats.

ClamAV before 0.93 allows remote attackers to bypass the scanning enging via a RAR file with an invalid version number, which cannot be parsed by ClamAV but can be extracted by Winrar.

The RAR VM (unrarvm.c) in Clam Antivirus (ClamAV) before 0.91 allows user-assisted remote attackers to cause a denial of service (crash) via a crafted RAR archive, resulting in a NULL pointer dereference.

Directory traversal vulnerability in clamd in Clam AntiVirus ClamAV before 0.90 allows remote attackers to overwrite arbitrary files via a .. (dot dot) in the id MIME header parameter in a multi-part message.

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.

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.
