Description This issue allows remote attackers to execute arbitrary code on affected installations of 7-Zip. User interaction is required to exploit this issue, where the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of SQFS files, resulting from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer.
