CVE-2015-1870
Description
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. The fix for this issue prevents non-privileged users from accessing any crash reports, even reports of crashes of processes owned by those users. Only administrators (the wheel group members) are allowed to access crash reports via the "System" tab in the ABRT GUI, or by running abrt-cli as root (that is, via "sudo abrt-cli" or "su -c abrt-cli").
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
