Security Bulletin

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

https://exchange.xforce.ibmcloud.com/vulnerabilities/107695 for the current 
score

CVSS Environmental Score*: Undefined
