CVE-2024-39312 is fixed in 3 products on 1 platform, first by DEBIAN-CVE-2024-39312, released July 8, 2024. It is not reported as exploited. Patch Radar priority: Routine.
Botan is a C++ cryptography library. X.509 certificates can identifyelliptic curves using either an object identifier or using explicitencoding of the parameters. A bug in the parsing of name constraintextensions in X.509 certificates meant that if the extension included bothpermitted subtrees and excluded subtrees, only the permitted subtree wouldbe checked. If a certificate included a name which was permitted by thepermitted subtree but also excluded by excluded subtree, it would beaccepted. Fixed in versions 3.5.0 and 2.19.5.
