[GLSA-200411-13] Portage, Gentoolkit: Temporary file vulnerabilities |
||
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 Networks Security ID: Vulnerability Assessment Copyright: (C) 2005 Michel Arboi |
