Description Agostino Sarubbo gentoo-dev 2016-08-25 09:23:47 UTC
From ${URL} :

It was found that an unproportionate amount of memory is allocated when parsing crafted certificates in 
libskba, which may lead to DoS. Moreover in libksba 1.3.4, allocated memory is uninitialized and could 
potentially contain sensitive data left in freed memory block.

Public via:

@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.
