Gentoo Linux Security Advisory

Title: libevent: User-assisted execution of arbitrary code (GLSA 201502-07)
Severity: normal
Exploitable: local, remote
Date: February 07, 2015
Bug(s): #535774
ID: 201502-07

Synopsis

Multiple integer overflow errors in libevent could result in
execution of arbitrary code or Denial of Service.


Background

libevent is a library to execute a function when a specific event occurs
on a file descriptor.


Affected Packages

Package: dev-libs/libevent
Vulnerable: < 2.0.22
Unaffected: >= 2.0.22
Architectures: All supported architectures


Description

Multiple integer overflow errors in libevent could cause a heap-based
buffer overflow.


Impact

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.


Workaround

There is no known workaround at this time.

Resolution

All libevent users should upgrade to the latest version:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-libs/libevent-2.0.22"
   


References

CVE-2014-6272
