Andrew McCreight, Christian Holler, Jon Coppeard, and Milan Sreckovic
discovered multiple memory safety issues in Firefox. If a user were
tricked in to opening a specially crafted website, an attacker could
potentially exploit these to cause a denial of service via application
crash, or execute arbitrary code with the privileges of the user invoking
Firefox. (CVE-2015-2708, CVE-2015-2709)
Atte Kettunen discovered a buffer overflow during the rendering of SVG
content with certain CSS properties in some circumstances. If a user were
tricked in to opening a specially crafted website, an attacker could
potentially exploit this to cause a denial of service via application
crash, or execute arbitrary code with the privileges of the user invoking
Firefox. (CVE-2015-2710)
Alex Verstak discovered that <meta name="referrer"> is ignored in some
circumstances. (CVE-2015-2711)
Dougall Johnson discovered an out of bounds read and write in asm.js. If
a user were tricked in to opening a specially crafted website, an
attacker could potentially exploit this to obtain sensitive information,
cause a denial of service via application crash, or execute arbitrary
code with the privileges of the user invoking Firefox. (CVE-2015-2712)
Scott Bell discovered a use-afer-free during the processing of text when
vertical text is enabled. If a user were tricked in to opening a specially
crafted website, an attacker could potentially exploit this to cause a
denial of service via application crash, or execute arbitrary code with
the privileges of the user invoking Firefox. (CVE-2015-2713)
Tyson Smith and Jesse Schwartzentruber discovered a use-after-free during
shutdown. An attacker could potentially exploit this to cause a denial of
service via application crash, or execute arbitrary code with the
privileges of the user invoking Firefox. (CVE-2015-2715)
Ucha Gobejishvili discovered a buffer overflow when parsing compressed XML
content. If a user were tricked in to opening a specially crafted website,
an attacker could potentially exploit this to cause a denial of service
via application crash, or execute arbitrary code with the privileges of
the user invoking Firefox. (CVE-2015-2716)
A buffer overflow and out-of-bounds read were discovered when parsing
metadata in MP4 files in some circumstances. If a user were tricked in to
opening a specially crafted website, an attacker could potentially exploit
this to cause a denial of service via application crash, or execute
arbitrary code with the privileges of the user invoking Firefox.
(CVE-2015-2717)
Mark Hammond discovered that when a trusted page is hosted within an
iframe in an untrusted page, the untrusted page can intercept webchannel
responses meant for the trusted page in some circumstances. If a user
were tricked in to opening a specially crafted website, an attacker could
exploit this to bypass origin restrictions. (CVE-2015-2718)
