Multiple F-Secure Anti-Virus LZH RAR archive security bypass
| fsecure-lzh-rar-security-bypass (34942) |  Low Risk |
Description:
Multiple F-Secure Anti-Virus applications could allow a remote attacker to bypass security restrictions, caused by improper parsing of LZH and RAR archives. By creating a specially-crafted LZH or RAR archive file containing a malicious archive file header field, an attacker could exploit this vulnerability to bypass scan detection, once the file is opened.
