Description
This security bulletin contains information about 8 secuirty vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2017-5373)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
Memory safety bugs were reported in Firefox 50.1 and Firefox ESR 45.6. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Thunderbird < 45.7, Firefox ESR < 45.7, and Firefox < 51.
2) Buffer overflow (CVE-ID: CVE-2017-5375)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
JIT code allocation can allow for a bypass of ASLR and DEP protections leading to potential memory corruption attacks. This vulnerability affects Thunderbird < 45.7, Firefox ESR < 45.7, and Firefox < 51.
3) Use-after-free (CVE-ID: CVE-2017-5376)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
Use-after-free while manipulating XSL in XSLT documents. This vulnerability affects Thunderbird < 45.7, Firefox ESR < 45.7, and Firefox < 51.
4) Information disclosure (CVE-ID: CVE-2017-5378)
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
Hashed codes of JavaScript objects are shared between pages. This allows for pointer leaks because an object's address can be discovered through hash codes, and also allows for data leakage of an object's content using these hash codes. This vulnerability affects Thunderbird < 45.7, Firefox ESR < 45.7, and Firefox < 51.
5) Use-after-free (CVE-ID: CVE-2017-5380)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
A potential use-after-free found through fuzzing during DOM manipulation of SVG content. This vulnerability affects Thunderbird < 45.7, Firefox ESR < 45.7, and Firefox < 51.
6) Input validation error (CVE-ID: CVE-2017-5383)
The vulnerability allows a remote non-authenticated attacker to manipulate data.
URLs containing certain unicode glyphs for alternative hyphens and quotes do not properly trigger punycode display, allowing for domain name spoofing attacks in the location bar. This vulnerability affects Thunderbird < 45.7, Firefox ESR < 45.7, and Firefox < 51.
7) Input validation error (CVE-ID: CVE-2017-5390)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
The JSON viewer in the Developer Tools uses insecure methods to create a communication channel for copying and viewing JSON or HTTP headers data, allowing for potential privilege escalation. This vulnerability affects Thunderbird < 45.7, Firefox ESR < 45.7, and Firefox < 51.
8) Use-after-free (CVE-ID: CVE-2017-5396)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
A use-after-free vulnerability in the Media Decoder when working with media files when some events are fired after the media elements are freed from memory. This vulnerability affects Thunderbird < 45.7, Firefox ESR < 45.7, and Firefox < 51.
