Description Adam Mariš 2017-04-18 10:57:39 UTC 
GnuTLS before 2017-02-20 has an out-of-bounds write caused by an integer overflow and heap-based buffer overflow related to the cdk_pkt_read function in opencdk/read-packet.c. This issue (which is a subset of the vendor's GNUTLS-SA-2017-3 report) is fixed in 3.5.10.

This issue affects only applications which utilize the OpenPGP certificate functionality of GnuTLS.
