GLSA-200506-13 : webapp-config: Insecure temporary file handling
Medium Nessus Plugin ID 18520
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200506-13 (webapp-config: Insecure temporary file handling)
Eric Romang discovered webapp-config uses a predictable temporary filename while processing certain options, resulting in a race condition.
Successful exploitation of the race condition would allow an attacker to disrupt the operation of webapp-config, or execute arbitrary shell commands with the privileges of the user running webapp-config. A local attacker could use a symlink attack to create or overwrite files with the permissions of the user running webapp-config.
There is no known workaround at this time.
SolutionAll webapp-config users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-admin/webapp-config-1.11'
