CentOS Errata and Security Advisory CESA-2013:0215
ABRT (Automatic Bug Reporting Tool) is a tool to help users to detect
defects in applications and to create a bug report with all the information
needed by a maintainer to fix it. It uses a plug-in system to extend its
functionality. libreport provides an API for reporting different problems
in applications to different bug targets, such as Bugzilla, FTP, and Trac.
It was found that the
/usr/libexec/abrt-action-install-debuginfo-to-abrt-cache tool did not
sufficiently sanitize its environment variables. This could lead to Python
modules being loaded and run from non-standard directories (such as /tmp/).
A local attacker could use this flaw to escalate their privileges to that
of the abrt user. (CVE-2012-5659)
A race condition was found in the way ABRT handled the directories used to
store information about crashes. A local attacker with the privileges of
the abrt user could use this flaw to perform a symbolic link attack,
possibly allowing them to escalate their privileges to root.
(CVE-2012-5660)
Red Hat would like to thank Martin Carpenter of Citco for reporting the
CVE-2012-5660 issue. CVE-2012-5659 was discovered by Miloslav Trmač of Red
Hat.
All users of abrt and libreport are advised to upgrade to these updated
packages, which correct these issues.
