unrar.c in libclamav in ClamAV before 0.90.3 and 0.91 before 0.91rc1 allows remote attackers to cause a denial of service (core dump) via a crafted RAR file with a modified vm_codesize value, which triggers a heap-based buffer overflow.

Integer signedness error in the (1) cab_unstore and (2) cab_extract functions in libclamav/cab.c in Clam AntiVirus (ClamAV) before 0.90.2 allow remote attackers to execute arbitrary code via a crafted CHM file that contains a negative integer, which passes a signed comparison and leads to a stack-based buffer overflow.

Multiple interpretation error in unspecified versions of ClamAV Antivirus allows remote attackers to bypass virus detection via a malicious executable in a specially crafted RAR file with malformed central and local headers, which can still be opened by products such as Winrar and PowerZip, even though they are rejected as corrupted by Winzip and BitZipper.
