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.

ClamAV before 0.93 allows remote attackers to cause a denial of service (CPU consumption) via a crafted ARJ archive, as demonstrated by the PROTOS GENOME test suite for Archive Formats.

Heap-based buffer overflow in pe.c in libclamav in ClamAV 0.92.1 allows remote attackers to execute arbitrary code via a crafted WWPack compressed PE binary.

Heap-based buffer overflow in spin.c in libclamav in ClamAV 0.92.1 allows remote attackers to execute arbitrary code via a crafted PeSpin packed PE binary with a modified length value.

Buffer overflow in the cli_scanpe function in libclamav (libclamav/pe.c) for ClamAV 0.92 and 0.92.1 allows remote attackers to execute arbitrary code via a crafted Upack PE file.

The unmew11 function in libclamav/mew.c in libclamav in ClamAV before 0.92.1 has unknown impact and attack vectors that trigger "heap corruption."

ClamAV 0.92 allows local users to overwrite arbitrary files via a symlink attack on (1) temporary files used by the cli_gentempfd function in libclamav/others.c or on (2) .ascii files used by sigtool, when utf16-decode is enabled.

ClamAV 0.92 does not recognize Base64 UUEncoded archives, which allows remote attackers to bypass the scanner via a Base64-UUEncoded file.
