CVE-2015-5287: ABRT abrt-hook-ccpp symlink attack on predictable core file (local root)

Exploited in the wild High 7.8 EPSS 5.0%

The abrt-hook-ccpp helper in the Automatic Bug Reporting Tool (ABRT) before 2.7.1 saved core dumps of programs whose name starts with 'abrt' to a predictable path such as /var/spool/abrt/abrt-hax-coredump or /var/tmp/abrt/abrt-hax-coredump and followed symlinks there, letting local users write files as root and escalate privileges. Red Hat fixed RHEL 7 in RHSA-2015:2505 (RHEL 6 is not affected). CISA added it to the Known Exploited Vulnerabilities catalog on 2026-08-26.

What to do now

Check whether you run the affected software and which version (commands below).
Install the fixed version for your system: see “Patch it” below.
Restart the ABRT daemon and core-dump hook services (or reboot) after updating.
Because this flaw is being exploited, also check the server for signs of compromise.

Affected and fixed versions

Affected:

ABRT before 2.7.1

Fixed in:

ABRT 2.7.1 (upstream commit 3c1b60cf 'ccpp: save abrt core files only to new files')

Am I affected?

rpm -q abrt abrt-addon-ccpp libreport

Patch it

Use the commands for your system. Distribution packages often keep an older version number with the fix backported, so compare with the fixed package versions in the table below, not only with the upstream version.

RHEL, AlmaLinux, Rocky, Oracle

sudo yum update abrt libreport

General update steps for every system are on the Linux and Unix & BSD pages; after updating, see which services to restart.
