Description
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.
