Doc Text:
A flaw was found in node-tar, a Tar utility for Node.js. This vulnerability allows a local attacker to potentially disclose sensitive information. When the .t (or .list) function is used with { sync: true } to read tar entry contents, and the tar file is concurrently modified on disk to a smaller size, the function may return uninitialized memory contents. This could lead to the exposure of arbitrary data.

Description OSIDB Bzimport 2025-10-30 18:01:42 UTC
node-tar is a Tar for Node.js. In 7.5.1, using .t (aka .list) with { sync: true } to read tar entry contents returns uninitialized memory contents if tar file was changed on disk to a smaller size while being read. This vulnerability is fixed in 7.5.2.
