Updated abrt packages that fix multiple security issues are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

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 to attack, or to overwrite arbitrary files on the system. (CVE-2015-3147)

Multiple directory traversal flaws were found in the abrt-dbus D-Bus service. A local attacker could use these flaws to read and write arbitrary files as the root user. (CVE-2015-3151)

It was discovered that the abrt-dbus D-Bus service did not properly check the validity of the problem directory argument in the ChownProblemDir, DeleteElement, and DeleteProblem methods. A local attacker could use this flaw to take ownership of arbitrary files and directories, or to delete files and directories as the root user.
(CVE-2015-3150)

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)

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

The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2015-1210 advisory.

    - harden against directory traversal, crafted symbolic links (rhbz#1212093)
    - avoid race-conditions in dump dir opening (rhbz#1212093)
    - Resolves: #1211966
