Name of the Vulnerable Software and Affected Versions scratchbox2 version 1.99.0.24

Description The issue allows local users to overwrite arbitrary files via a symlink attack on temporary files, specifically (a) /tmp/dpkg.#####.tmp, (b) /tmp/missing deps.#####, and (c) /tmp/sb2-pkg-chk.$tstamp.#####, related to the dpkg-checkbuilddeps and sb2-check-pkg-mappings scripts.

Recommendations For scratchbox2 version 1.99.0.24, consider restricting access to the temporary files /tmp/dpkg.#####.tmp, /tmp/missing deps.#####, and /tmp/sb2-pkg-chk.$tstamp.##### to prevent a symlink attack. Additionally, as a temporary workaround, consider disabling the dpkg-checkbuilddeps and sb2-check-pkg-mappings scripts until a patch is available. At the moment, there is no information about a newer version that contains a fix for this issue.
