[MFSA-2023-41] Security Vulnerabilities fixed in Firefox 118
CVE-2023-5168: Out-of-bounds write in FilterNodeD2D1 (high)
A compromised content process could have provided malicious data to <code>FilterNodeD2D1</code> resulting in an out-of-bounds write, leading to a potentially exploitable crash in a privileged process.
This bug only affects Firefox on Windows. Other operating systems are unaffected.CVE-2023-5169: Out-of-bounds write in PathOps (high)
A compromised content process could have provided malicious data in a <code>PathRecording</code> resulting in an out-of-bounds write, leading to a potentially exploitable crash in a privileged process.CVE-2023-5170: Memory leak from a privileged process (high)
In canvas rendering, a compromised content process could have caused a surface to change unexpectedly, leading to a memory leak of a privileged process. This memory leak could be used to effect a sandbox escape if the correct data was leaked.CVE-2023-5171: Use-after-free in Ion Compiler (high)
During Ion compilation, a Garbage Collection could have resulted in a use-after-free condition, allowing an attacker to write two NUL bytes, and cause a potentially exploitable crash.CVE-2023-5172: Memory Corruption in Ion Hints (high)
A hashtable in the Ion Engine could have been mutated while there was a live interior reference, leading to a potential use-after-free and exploitable crash.CVE-2023-5173: Out-of-bounds write in HTTP Alternate Services (moderate)
In a non-standard configuration of Firefox, an integer overflow could have occurred based on network traffic (possibly under influence of a local unprivileged webpage), leading to an out-of-bounds write to privileged process memory.
This bug only affects Firefox if a non-standard preference allowing non-HTTPS Alternate Services (<code>network.http.altsvc.oe</code>) is enabled.CVE-2023-5174: Double-free in process spawning on Windows (moderate)
If Windows failed to duplicate a handle during process creation, the sandbox code may have inadvertently freed a pointer twice, resulting in a use-after-free and a potentially exploitable crash.
This bug only affects Firefox on Windows when run in non-standard configurations (such as using <code>runas</code>). Other operating systems are unaffected.CVE-2023-5175: Use-after-free of ImageBitmap during process shutdown (low)
During process shutdown, it was possible that an <code>ImageBitmap</code> was created that would later be used after being freed from a different codepath, leading to a potentially exploitable crash.CVE-2023-5176: Memory safety bugs fixed in Firefox 118, Firefox ESR 115.3, and Thunderbird 115.3 (high)
Memory safety bugs present in Firefox 117, Firefox ESR 115.2, and Thunderbird 115.2. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code.
