GLSA-200508-05 : Heartbeat: Insecure temporary file creation
Low Nessus Plugin ID 19389
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200508-05 (Heartbeat: Insecure temporary file creation)
Eric Romang has discovered that Heartbeat insecurely creates temporary files with predictable filenames.
A local attacker could create symbolic links in the temporary file directory, pointing to a valid file somewhere on the filesystem. When a vulnerable script is executed, this could lead to the file being overwritten with the rights of the user running the affected application.
There is no known workaround at this time.
SolutionAll Heartbeat users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=sys-cluster/heartbeat-1.2.3-r1'
