Summary
Vulnerabilities were discovered in GSKit. IBM Content Collector for SAP
Applications uses GSKit and addressed the applicable CVEs.
Vulnerability Details
CVEID: CVE-2015-7421
DESCRIPTION: A vulnerability in GSKit could allow a remote attacker to obtain
sensitive information. The internal ICC PRNG pool state is duplicated during a
fork() system call operation which results in a period of time where child
processes may generate identical PRNG output to the parent. This may allow
possible attacks related to predicable state which an attacker could exploit.
CVSS Base Score: 3.7

score
