Description Andrej Nemec 2016-02-24 15:33:34 UTC 
When evaluating a certificate path, if a loop in the certificate chain was encountered (for instance where C1 certifies C2, which certifies C1) an infinite loop would occur eventually resulting in memory exhaustion.

Comment 1 Thomas Moschny 2016-04-29 18:34:05 UTC 
CVE-2015-7825 only affects 1.11.X for 6<=X<22.

In Fedora/EPEL, we have 1.8.X and 1.10.X (i.e. stable) versions.
