Vulnerability Title
Libarchive: libarchive: information disclosure via heap out-of-bounds read in rar archive processing
来源: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in libarchive. This heap out-of-bounds read vulnerability exists in the RAR archive processing logic due to improper validation of the LZSS sliding window size after transitions between compression methods. A remote attacker can exploit this by providing a specially crafted RAR archive, leading to the disclosure of sensitive heap memory information without requiring authentication or user interaction.
