Security Bulletin: GNU C library (glibc) vulnerability affects IBM QRadar SIEM and Incident Forensics (CVE-2015-7547)
A GNU C library (glibc) stack-based buffer overflow in getaddrinfo() vulnerability affects IBM QRadar SIEM and Incident Forensics.
DESCRIPTION: GNU C Library (glibc) is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the nss_dns backend for the getaddrinfo() function when performing dual A/AAAA DNS queries. By sending a specially crafted DNS response, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
