Synopsis ========
A vulnerability in Exim may allow local users to gain root privileges.
Background ==========
Exim is a message transfer agent (MTA) developed at the University of Cambridge for use on Unix systems connected to the Internet.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 mail-mta/exim < 4.89-r1 >= 4.89-r1
Description ===========
Exim supports the use of multiple "-p" command line arguments causing a memory leak. This could lead to a stack-clash in user-space and as result the attacker can, "clash" or "smash" the stack or another memory region, or "jump" over the stack guard-page.
Impact ======
A local attacker could obtain root privileges.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All Exim users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=mail-mta/exim-4.89-r1"
