The Ubuntu security team deemed this advisory irrelevant for Ubuntu:15.10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream tor package and not the tor package as distributed by Ubuntu.
buf_pullup in Tor before 0.2.4.26 and 0.2.5.x before 0.2.5.11 does not properly handle unexpected arrival times of buffers with invalid layouts, which allows remote attackers to cause a denial of service (assertion failure and daemon exit) via crafted packets.
