Bug 620256 (CVE-2017-9022, CVE-2017-9023) – <net-vpn/strongswan-5.5.3: multiple vulnerabilities

• Product: Gentoo Security
• Status: RESOLVED FIXED

[Description Agostino Sarubbo 2017-05-31 14:31:08 UTC]

From https://bugzilla.redhat.com/show_bug.cgi?id=1457121:

It was found that RSA public keys passed to the gmp plugin aren't validated sufficiently before attempting signature verification, so that invalid input might lead to a floating point exception and 
crash of the process. A certificate with an appropriately prepared public key sent by a peer could be used for a denial-of-service attack.

From https://bugzilla.redhat.com/show_bug.cgi?id=1457122:


It was found that ASN.1 CHOICE types are not correctly handled by the ASN.1 parser when parsing X.509 certificates with extensions that use such types. This could lead to infinite looping of the thread 
parsing a specifically crafted certificate.

@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.

5.5.2 has been added to the tree, and 5.5.1 has been removed.
Please stabilize, so we can remove the last old version.

Please note that according to:
https://strongswan.org/blog/2017/05/30/strongswan-vulnerability-(cve-2017-9022).html
5.5.2 is still a vulnerable version, 5.5.3 is actually required.

Indeed - I have changed it to 5.5.3 instead :)
