ClamAV before 0.98.7 allows remote attackers to cause a denial of service (crash) via a crafted petite packed file.

ClamAV before 0.98.6 allows remote attackers to have unspecified impact via a crafted upx packer file, related to a "heap out of bounds condition."

ClamAV before 0.98.6 allows remote attackers to have unspecified impact via a crafted upack packer file, related to a "heap out of bounds condition."

ClamAV before 0.98.6 allows remote attackers to have unspecified impact via a crafted (1) Yoda's crypter or (2) mew packer file, related to a "heap out of bounds condition."

ClamAV before 0.98.6 allows remote attackers to cause a denial of service (crash) via a crafted petite packer file, related to an "incorrect compiler optimization."

Heap-based buffer overflow in the cli_scanpe function in libclamav/pe.c in ClamAV before 0.98.5 allows remote attackers to cause a denial of service (crash) via a crafted y0da Crypter PE file.

clamscan in ClamAV before 0.98.5, when using -a option, allows remote attackers to cause a denial of service (crash) as demonstrated by the jwplayer.js file.

Integer underflow in the cli_scanpe function in pe.c in ClamAV before 0.97.8 allows remote attackers to cause a denial of service (crash) via a skewed offset larger than the size of the PE section in a UPX packed executable, which triggers an out-of-bounds read.

The TAR file parser in ClamAV 0.96.4 and Quick Heal (aka Cat QuickHeal) 11.00 allows remote attackers to bypass malware detection via a POSIX TAR file with an initial [aliases] character sequence.
