GLSA-201502-07 : libevent: User-assisted execution of arbitrary code
High Nessus Plugin ID 81230
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-201502-07 (libevent: User-assisted execution of arbitrary code)
Multiple integer overflow errors in libevent could cause a heap-based buffer overflow.
A context-dependent attacker could cause an application linked against libevent to pass an excessively long input through evbuffer, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.
There is no known workaround at this time.
SolutionAll libevent users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-libs/libevent-2.0.22'
