Description
This security bulletin contains information about 1 security vulnerability.
1) Memory corruption (CVE-ID: CVE-2018-10811)
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists in the Internet Key Exchange Version 2 (IKEv2) key derivation of strongSwan due to insufficient initialization of the variable that stores the SKEYSEED for IKEv2 key derivation before using the negotiated pseudorandom function (PRF). A remote attacker can trigger a key derivation failure and cause the affected software to clear the uninitialized memory that may lead to crash.
