7-Zip < 24.01 Heap-based Buffer Overflow

high Nessus Plugin ID 209231

Language:

Synopsis

The 7-zip instance installed on the remote host is affected by a heap based buffer overflow vulnerability.

Description

The version of 7-Zip installed on the remote Windows host is below 24.01. It is, therefore, affected by multiple vulnerabilities:

 - The NtfsHandler.cpp NTFS handler in 7-Zip before 24.01 (for 7zz) contains a heap-based buffer overflow that allows an attacker to overwrite two bytes at multiple offsets beyond the allocated buffer size:
 buffer+512*i-2, for i=9, i=10, i=11, etc. (CVE-2023-52168)

 - The NtfsHandler.cpp NTFS handler in 7-Zip before 24.01 (for 7zz) contains an out-of-bounds read that allows an attacker to read beyond the intended buffer. The bytes read beyond the intended buffer are presented as a part of a filename listed in the file system image. This has security relevance in some known web-service use cases where untrusted users can upload files and have them extracted by a server-side 7-Zip process. (CVE-2023-52169)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to 7-zip version 24.01 or later.
