Synopsis

The remote Mac OS X host contains a web browser that is affected by multiple vulnerabilities.

Description

The version of Firefox ESR installed on the remote Mac OS X host is prior to 38.2. It is, therefore, affected by the following vulnerabilities :

- Multiple memory corruption issues exist that allow a remote attacker, via a specially crafted web page, to corrupt memory and potentially execute arbitrary code.
(CVE-2015-4473)

- An out-of-bounds read error exists in the PlayFromAudioQueue() function due to improper handling of mismatched sample formats. A remote attacker can exploit this, via a specially crafted MP3 file, to disclose memory contents or execute arbitrary code.
(CVE-2015-4475)

- A same-origin policy bypass vulnerability exists due to non-configurable properties being redefined in violation of the ECMAScript 6 standard during JSON parsing. A remote attacker can exploit this, by editing these properties to arbitrary values, to bypass the same-origin policy. (CVE-2015-4478)

- Multiple integer overflow conditions exist due to improper validation of user-supplied input when handling 'saio' chunks in MPEG4 video. A remote attacker can exploit this, via a specially crafted MPEG4 file, to execute arbitrary code. (CVE-2015-4479)

- An integer overflow condition exists in the bundled libstagefright component when handling H.264 media content. A remote attacker can exploit this, via a specially crafted MPEG4 file, to execute arbitrary code.
(CVE-2015-4480)

- An out-of-bounds write error exists due to an array indexing flaw in the mar_consume_index() function when handling index names in MAR files. An attacker can exploit this to execute arbitrary code. (CVE-2015-4482)

- A denial of service vulnerability exists when handling JavaScript using shared memory without properly gating access to Atomics and SharedArrayBuffer views. An attacker can exploit this to crash the program, resulting in a denial of service condition.
(CVE-2015-4484)

- A heap-based buffer overflow condition exists in the resize_context_buffers() function due to improper validation of user-supplied input. A remote attacker can exploit this, via specially crafted WebM content, to cause a heap-based buffer overflow, resulting in the execution of arbitrary code. (CVE-2015-4485)

- A heap-based buffer overflow condition exists in the decrease_ref_count() function due to improper validation of user-supplied input. A remote attacker can exploit this, via specially crafted WebM content, to cause a heap-based buffer overflow, resulting in the execution of arbitrary code. (CVE-2015-4486)

- A buffer overflow condition exists in the ReplacePrep() function. A remote attacker can exploit this to cause a buffer overflow, resulting in the execution of arbitrary code. (CVE-2015-4487)

- A use-after-free error exists in the operator=() function. An attacker can exploit this to dereference already freed memory, resulting in the execution of arbitrary code. (CVE-2015-4488)

- A memory corruption issue exists in the nsTArray_Impl() function due to improper validation of user-supplied input during self-assignment. An attacker can exploit this to corrupt memory, resulting in the execution of arbitrary code. (CVE-2015-4489)

- A use-after-free error exists in the XMLHttpRequest::Open() function due to improper handling of recursive calls. An attacker can exploit this to dereference already freed memory, resulting in the execution of arbitrary code. (CVE-2015-4492)

- An integer underflow condition exists in the bundled libstagefright library. An attacker can exploit this to crash the application, resulting in a denial of service condition. (CVE-2015-4493)

Solution

Upgrade to Firefox ESR 38.2 or later.
