GLSA-200503-14 : KDE dcopidlng: Insecure temporary file creation
Low Nessus Plugin ID 17288
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200503-14 (KDE dcopidlng: Insecure temporary file creation)
Davide Madrisan has discovered that the dcopidlng script creates temporary files in a world-writable directory with predictable names.
A local attacker could create symbolic links in the temporary files directory, pointing to a valid file somewhere on the filesystem.
When dcopidlng is executed, this would result in the file being overwritten with the rights of the user running the utility, which could be the root user.
There is no known workaround at this time.
SolutionAll kdelibs users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose kde-base/kdelibs
