Updated firefox packages fix security vulnerabilities:

Multiple memory safety issues in Firefox were discovered. 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-2015-7201).

Ronald Crane discovered a buffer overflow through code inspection. 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-2015-7205).

Looben Yang discovered a use-after-free in WebRTC when closing channels 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-2015-7210).

Abhishek Arya discovered an integer overflow when allocating large textures. 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-2015-7212).

Ronald Crane dicovered an integer overflow when processing MP4 format video 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-2015-7213).

Tsubasa Iinuma discovered a way to bypass same-origin restrictions using data: and view-source: URLs. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to obtain sensitive information and read local files (CVE-2015-7214).

Gerald Squelart discovered an integer underflow in the libstagefright library when parsing MP4 format video 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-2015-7222).
