An update for strongswan is now available for openEuler-20.03-LTS-SP1 and openEuler-20.03-LTS-SP2 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2021-1408 Final 1.0 1.0 2021-10-30 Initial 2021-10-30 2021-10-30 openEuler SA Tool V1.0 2021-10-30 strongswan security update An update for strongswan is now available for openEuler-20.03-LTS-SP1 and openEuler-20.03-LTS-SP2. The strongSwan IPsec implementation supports both the IKEv1 and IKEv2 key exchange protocols in conjunction with the native NETKEY IPsec stack of the Linux kernel. Security Fix(es): The gmp plugin in strongSwan before 5.9.4 has a remote integer overflow via a crafted certificate with an RSASSA-PSS signature. For example, this can be triggered by an unrelated self-signed CA certificate sent by an initiator. Remote code execution cannot occur.(CVE-2021-41990) The in-memory certificate cache in strongSwan before 5.9.4 has a remote integer overflow upon receiving many requests with different certificates to fill the cache and later trigger the replacement of cache entries. The code attempts to select a less-often-used cache entry by means of a random number generator, but this is not done correctly. Remote code execution might be a slight possibility.(CVE-2021-41991) An update for strongswan is now available for openEuler-20.03-LTS-SP1 and openEuler-20.03-LTS-SP2. openEuler Security has rated this update as having a security impact of high.
