(RHSA-2015:1210) Moderate: abrt security update

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.

It was found that ABRT was vulnerable to multiple race condition and
symbolic link flaws. A local attacker could use these flaws to potentially
escalate their privileges on the system. (CVE-2015-3315)

It was discovered that the kernel-invoked coredump processor provided by
ABRT wrote core dumps to files owned by other system users. This could
result in information disclosure if an application crashed while its
current directory was a directory writable to by other users (such as
/tmp). (CVE-2015-3142)

It was discovered that the default event handling scripts installed by ABRT
did not handle symbolic links correctly. A local attacker with write access
to an ABRT problem directory could use this flaw to escalate their
privileges. (CVE-2015-1869)

It was found that the ABRT event scripts created a user-readable copy of an
sosreport file in ABRT problem directories, and included excerpts of
/var/log/messages selected by the user-controlled process name, leading to
an information disclosure. (CVE-2015-1870)

It was discovered that, when moving problem reports between certain
directories, abrt-handle-upload did not verify that the new problem
directory had appropriate permissions and did not contain symbolic links.
An attacker able to create a crafted problem report could use this flaw to
expose other parts of ABRT, or to overwrite arbitrary files on the system.
(CVE-2015-3147)

It was discovered that the abrt-action-install-debuginfo-to-abrt-cache
helper program did not properly filter the process environment before
invoking abrt-action-install-debuginfo. A local attacker could use this
flaw to escalate their privileges on the system. (CVE-2015-3159)

The CVE-2015-1869, CVE-2015-1870, CVE-2015-3142, CVE-2015-3147, and
CVE-2015-3159 issues were discovered by Florian Weimer of Red Hat
Product Security.

All users of abrt are advised to upgrade to these updated packages, which
correct these issues.
