Description
This security bulletin contains information about 1 vulnerability.
1) Cryptographic issues (CVE-ID: CVE-2013-4350)
CWE-ID: CWE-310 - Cryptographic Issues
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The IPv6 SCTP implementation in net/sctp/ipv6.c in the Linux kernel through 3.11.1 uses data structures and function calls that do not trigger an intended configuration of IPsec encryption, which allows remote attackers to obtain sensitive information by sniffing the network.
Remediation
Install update from vendor's website.
