CVE-2023-52169: CVE-2023-52168, CVE-2023-52169: buffer overflow, over-ad vulnerabilities in the 7-Zip archiver
First published: Wed Jul 03 2024(Updated: )
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.
