Description
This security bulletin contains information about 1 security vulnerability.
1) Buffer overflow (CVE-ID: CVE-2016-1245)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
It was discovered that the zebra daemon in Quagga before 1.0.20161017 suffered from a stack-based buffer overflow when processing IPv6 Neighbor Discovery messages. The root cause was relying on BUFSIZ to be compatible with a message size; however, BUFSIZ is system-dependent.
Remediation
Install update from vendor's website.
