SCA: security update for github.com/ulikunitz/xz (GHSA-jc7w-c686-c4v9)

medium Tenable Self-Hosted Container Security Plugin ID 435147

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - xz is a pure golang package for reading and writing xz-compressed files. Prior to version 0.5.14, it is
 possible to put data in front of an LZMA-encoded byte stream without detecting the situation while reading
 the header. This can lead to increased memory consumption because the current implementation allocates the
 full decoding buffer directly after reading the header. The LZMA header doesn't include a magic number or
 has a checksum to detect such an issue according to the specification. Note that the code recognizes the
 issue later while reading the stream, but at this time the memory allocation has already been done. This
 issue has been patched in version 0.5.14. (CVE-2025-58058)
