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

Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links 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. 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 ABRT debug information installer (abrt-action-install-debuginfo-to-abrt-cache) did not use temporary directories in a secure way. A local attacker could use the flaw to create symbolic links and files at arbitrary locations as the abrt user. (CVE-2015-5273)

It was discovered that the kernel-invoked coredump processor provided by ABRT did not handle symbolic links correctly when writing core dumps of ABRT programs to the ABRT dump directory (/var/spool/abrt). A local attacker with write access to an ABRT problem directory could use this flaw to escalate their privileges. (CVE-2015-5287)

It was found that ABRT may have exposed unintended information to Red Hat Bugzilla during crash reporting. A bug in the libreport library caused changes made by a user in files included in a crash report to be discarded. As a result, Red Hat Bugzilla attachments may contain data that was not intended to be made public, including host names, IP addresses, or command line options. (CVE-2015-5302)

This flaw did not affect default installations of ABRT on Red Hat Enterprise Linux as they do not post data to Red Hat Bugzilla. This feature can however be enabled, potentially impacting modified ABRT instances.

As a precaution, Red Hat has identified bugs filed by such non-default Red Hat Enterprise Linux users of ABRT and marked them private.

Red Hat would like to thank Philip Pettersson of Samsung for reporting the CVE-2015-5273 and CVE-2015-5287 issues. The CVE-2015-5302 issue was discovered by Bastien Nocera of Red Hat.

All users of abrt and libreport are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

Updated libreport packages that fix one security issue are now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having Moderate 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.

libreport provides an API for reporting different problems in applications to different bug targets, such as Bugzilla, FTP, and Trac. ABRT (Automatic Bug Reporting Tool) uses libreport.

It was found that ABRT may have exposed unintended information to Red Hat Bugzilla during crash reporting. A bug in the libreport library caused changes made by a user in files included in a crash report to be discarded. As a result, Red Hat Bugzilla attachments may contain data that was not intended to be made public, including host names, IP addresses, or command line options. (CVE-2015-5302)

This flaw did not affect default installations of ABRT on Red Hat Enterprise Linux as they do not post data to Red Hat Bugzilla. This feature can however be enabled, potentially impacting modified ABRT instances.

As a precaution, Red Hat has identified bugs filed by such non-default Red Hat Enterprise Linux users of ABRT and marked them private.

This issue was discovered by Bastien Nocera of Red Hat.

All users of libreport are advised to upgrade to these updated packages, which corrects this issue.
