[MFSA-2023-42] Security Vulnerabilities fixed in Firefox ESR 115.3
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-2023-5171: 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-2023-5174: 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-2023-5176: 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.
