Description

An update for procps is now available for Red Hat Enterprise Linux 6.6 Advanced Update Support and Red Hat Enterprise Linux 6.6 Telco Extended Update Support.

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

The procps packages contain a set of system utilities that provide system information. The procps packages include the following utilities: ps, free, skill, pkill, pgrep, snice, tload, top, uptime, vmstat, w, watch, pwdx, sysctl, pmap, and slabtop.

Security Fix(es) :

  • procps-ng, procps: Integer overflows leading to heap overflow in file2strvec (CVE-2018-1124)

  • procps-ng, procps: incorrect integer size in proc/alloc.* leading to truncation / integer overflow issues (CVE-2018-1126)

For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.

Red Hat would like to thank Qualys Research Labs for reporting these issues.
