CVE-2018-1125

procps-ng en versiones anteriores a la 3.3.15 es vulnerable a un desbordamiento de búfer basado en pila en pgrep. Esta vulnerabilidad se mitiga mediante FORTIFY, ya que implica el uso de strncat() en una cadena asignada a la pila. Cuando pgrep se compila con FORTIFY (como en Red Hat Enterprise Linux y Fedora), el impacto se limita a un cierre inesperado.

It was discovered that the procps-ng top utility incorrectly read its configuration file from the current working directory. A local attacker could possibly use this issue to escalate privileges. It was discovered that the procps-ng ps tool incorrectly handled memory. A local user could possibly use this issue to cause a denial of service. It was discovered that libprocps incorrectly handled the file2strvec function. A local attacker could possibly use this to execute arbitrary code. Various other issues were also addressed.
