Vulnerability Assessment Details

[GLSA-200411-13] Portage, Gentoolkit: Temporary file vulnerabilities

Vulnerability Assessment Summary
Portage, Gentoolkit: Temporary file vulnerabilities

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200411-13
(Portage, Gentoolkit: Temporary file vulnerabilities)

dispatch-conf and qpkg use predictable filenames for temporary files.

Impact

A local attacker could create symbolic links in the temporary files
directory, pointing to a valid file somewhere on the filesystem. When an
affected script is called, this would result in the file to be overwritten
with the rights of the user running the dispatch-conf or qpkg, which could
be the root user.

Workaround

There is no known workaround at this time.

Solution:
All Portage users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-apps/portage-2.0.51-r3"
All Gentoolkit users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-portage/gentoolkit-0.2.0_pre8-r1"

Network Security Threat Level: Medium
