CVE-2023-52169: 7-Zip

High severity, CVSS 8.2. EPSS: 1% chance of exploitation in the next 30 days.

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.

Affected products

• 7-Zip 7-Zip: before 24.01 (fixed in 24.01)
