Description Huzaifa S. Sidhpurwala 2015-10-07 06:03:50 UTC 
Google security engineer Ryan Sleevi reported an integer overflow in the Netscape Portable Runtime (NSPR) due to a lack of checks during memory allocation. This leads to a potentially exploitable crash. This issue is fixed in NSPR 4.10.10. The NSPR library is a required component of NSS.
