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/chmunpack.c in the chm-parser in ClamAV before 0.94 allows remote attackers to cause a denial of service (application crash) via a malformed CHM file, related to an "invalid memory access."

libclamav/petite.c in ClamAV before 0.93.3 allows remote attackers to cause a denial of service via a malformed Petite file that triggers an out-of-bounds memory access. NOTE: this issue exists because of an incomplete fix for CVE-2008-2713.
