Moderate: p7zip security update (Amazon Linux 2023)

Published Aug 14, 2024 · Updated Aug 19, 2024

Summary

Package updates are available for Amazon Linux 2023 that fix the following vulnerabilities: CVE-2023-52169: 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-2023-52168: 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.
