Description:
Moritz Jodeit has reported a vulnerability in ClamAV, which can be exploited by malicious people to cause a DoS (Denial of Service) or potentially compromise a vulnerable system.
The vulnerability is caused due to an off-by-one error within the "get_unicode_name()" function in libclamav/vba_extract.c. This can be exploited to cause a heap-based buffer overflow with a zero byte via a specially crafted VBA project.
Successful exploitation may allow execution of arbitrary code.
