Vulnerability Title
Libarchive: double-free vulnerability in rar5 decompression logic via dangling filtered_buf pointer in init_unpack()
Vulnerability Description
A double free issue has been identified in libarchive's RAR5 reader. During parsing of a specially crafted RAR5 archive, the filtered_buf pointer may remain stale after being freed during unpacking state reinitialization. Subsequent processing of another archive entry can trigger a second free of the same memory region, resulting in a double-free condition. Successful exploitation may cause applications using the vulnerable libarchive API to terminate unexpectedly, leading to a denial of service.

Vulnerability Title
libarchive 资源管理错误漏洞
Vulnerability Description
libarchive是libarchive团队开源的一款多格式存档和压缩库。 libarchive存在资源管理错误漏洞,该漏洞源于RAR5解析器中的双重释放问题,在解析特制RAR5存档时,filtered_buf指针在解压状态重新初始化释放后可能未重置,后续处理另一个归档条目时可能导致同一内存区域被二次释放,成功利用可能导致使用易受攻击的libarchive API的应用程序意外终止,导致拒绝服务。
