SCA: security update for diff (GHSA-73rr-hh4g-fpgx)

medium Tenable Self-Hosted Container Security Plugin ID 436765

Description

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

 - jsdiff is a JavaScript text differencing implementation. Prior to versions 8.0.3, 5.2.2, 4.0.4, and 3.5.1,
 attempting to parse a patch whose filename headers contain the line break characters `\r`, `\u2028`, or
 `\u2029` can cause the `parsePatch` method to enter an infinite loop. It then consumes memory without
 limit until the process crashes due to running out of memory. Applications are therefore likely to be
 vulnerable to a denial-of-service attack if they call `parsePatch` with a user-provided patch as input. A
 large payload is not needed to trigger the vulnerability, so size limits on user input do not provide any
 protection. Furthermore, some applications may be vulnerable even when calling `parsePatch` on a patch
 generated by the application itself if the user is nonetheless able to control the filename headers (e.g.
 by directly providing the filenames of the files to be diffed). The `applyPatch` method is similarly
 affected if (and only if) called with a string representation of a patch as an argument, since under the
 hood it parses that string using `parsePatch`. Other methods of the library are unaffected. Finally, a
 second and lesser interdependent bug - a ReDOS - also exhibits when those same line break characters are
 present in a patch's *patch* header (also known as its "leading garbage"). A maliciously-crafted patch
 header of length *n* can take `parsePatch` O(*n*³) time to parse. Versions 8.0.3, 5.2.2, 4.0.4, and 3.5.1
 contain a fix. As a workaround, do not attempt to parse patches that contain any of these characters:
 `\r`, `\u2028`, or `\u2029`. (CVE-2026-24001)
