Vulnerability Title
NanaZip: Unbounded memory allocation (DoS) in NanaZip UFS parser via unvalidated fs_bsize/fs_fsize superblock fields
Vulnerability Description
NanaZip is the 7-Zip derivative intended for the modern Windows experience. Prior to 6.5.1749.0, NanaZip's UFS and FFS image handler in NanaZip.Codecs.Archive.Ufs.cpp validates the superblock block size only against the MINBSIZE lower bound and does not validate the fs_fsize fragment size, allowing attacker-controlled 32-bit fields to flow into indirect-block, directory, and extraction buffer allocations. A tiny crafted UFS image can force multi-gigabyte allocations during open or extraction, causing memory exhaustion or process termination. This issue is fixed in version 6.5.1749.0.

M2Team NanaZip 资源管理错误漏洞
Vulnerability Description
m2team nanazip是m2team团队开源的一个压缩软件。 M2Team NanaZip 6.5.1749.0之前版本存在资源管理错误漏洞,该漏洞源于对UFS和FFS图像处理程序中的超块块大小验证不完整且未验证fs_fsize片段大小,导致攻击者控制的32位字段流入间接块、目录和提取缓冲区分配。特制的UFS镜像在打开或提取过程中可能导致内存耗尽或进程终止。
