GLSA-200809-12 : Newsbeuter: User-assisted execution of arbitrary code
Medium Nessus Plugin ID 34258
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200809-12 (Newsbeuter: User-assisted execution of arbitrary code)
J.H.M. Dassen reported that the open-in-browser command does not properly escape shell metacharacters in the URL before passing it to system().
A remote attacker could entice a user to open a feed with specially crafted URLs, possibly resulting in the remote execution of arbitrary shell commands with the privileges of the user running the application.
There is no known workaround at this time.
SolutionAll Newsbeuter users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-news/newsbeuter-1.2'
