Package : firefox
Type : multiple issues

Link : https://wiki.archlinux.org/index.php/CVE

- CVE-2015-0817 (arbitrary remote code execution):
Security researcher ilxu1a reported, through HP Zero Day Initiative's
Pwn2Own contest, a flaw in Mozilla's implementation of typed array
management of bounds checking for heap access. This flaw can be
leveraged into the reading and writing of memory allowing for arbitary
code execution on the local system.
- CVE-2015-0818 (same-origin policy bypass):
Security researcher Mariusz Mlynski reported, through HP Zero Day
Initiative's Pwn2Own contest, a method to run arbitrary scripts in a
privileged context. This bypassed the same-origin policy protections by
using a flaw in the processing of SVG format content navigation.
A remote attacker can bypass the same-origin policy or execute arbitrary
code with the privilege of the browser.
