Severity
+ High
Remote
+ Remote
Type
+ Arbitrary code execution
Description
+ A memory corruption vulnerability has been found in the Audio Buffer component of Firefox < 65.0. When JavaScript is used to create and manipulate an audio buffer, a potentially exploitable crash may occur because of a compartment mismatch in some situations.

Severity
+ High
Remote
+ Remote
Type
+ Arbitrary code execution
Description
+ A memory corruption and out-of-bounds read have been found in Firefox < 65.0, that can occur when the buffer of a texture client is freed while it is still in use during graphic operations. This results in a potentially exploitable crash and the possibility of reading from the memory of the freed buffers.

CVE-2018-18505 created at 25 Sep 2019 19:31:40
Severity
+ High
Remote
+ Local
Type
+ Privilege escalation
Description
+ A privilege escalation issue has been found in Firefox < 65.0. An earlier fix for an Inter-process Communication (IPC) vulnerability, CVE-2011-3079, added authentication to communication between IPC endpoints and server parents during IPC process creation. This authentication is insufficient for channels created after the IPC process is started, leading to the authentication not being correctly applied to later channels. This could allow for a sandbox escape through IPC channels due to lack of message validation in the listener process.

CVE-2018-18506 created at 25 Sep 2019 19:31:40
Severity
+ Medium
Remote
+ Remote
Type
+ Access restriction bypass
Description
+ When proxy auto-detection is enabled in Firefox < 65.0, if a web server serves a Proxy Auto-Configuration (PAC) file or if a PAC file is loaded locally, this PAC file can specify that requests to the localhost are to be sent through the proxy to another server. This behavior is disallowed by default when a proxy is manually configured, but when enabled could allow for attacks on services and tools that bind to the localhost for networked behavior if they are accessed through browsing.

Severity
+ High
Remote
+ Remote
Type
+ Insufficient validation
Description
+ A flaw during verification of certain S/MIME signatures causes emails to be shown in Thunderbird before 60.5.1 as having a valid digital signature, even if the shown message contents aren't covered by the signature. The flaw allows an attacker to reuse a valid S/MIME signature to craft an email message with arbitrary content.

Type
+ Same-origin policy bypass
Description
+ A cross-origin theft of images issue has been found in the ImageBitmapRenderingContext component of firefox 65.0, where cross-origin images can be read from a canvas element in violation of the same-origin policy using the transferFromImageBitmap method. The issue has been fixed in 65.0.1 and versions prior to 65.0 were not affected.

Severity
+ Medium
Remote
+ Remote
Type
+ Denial of service
Description
+ An Invalid Memory Address Dereference exists in the function elf_end in libelf in elfutils through v0.174. Although eu-size is intended to support ar files inside ar files, handle_ar in size.c closes the outer ar file before handling all inner entries. The vulnerability allows attackers to cause a denial of service (application crash) with a crafted ELF file.

Type
+ Denial of service
Description
+ Divide-by-zero vulnerabilities in the function arlib_add_symbols() in arlib.c in elfutils 0.174 allow remote attackers to cause a denial of service (application crash) with a crafted ELF file, as demonstrated by eu-ranlib, because a zero sh_entsize is mishandled.
