Ubuntu 22.04 LTS / 23.04 : SpiderMonkey vulnerabilities (USN-6120-1)

high Nessus Plugin ID 176492

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6120-1 advisory.

 - Cross-compartment wrappers wrapping a scripted proxy could have caused objects from other compartments to be stored in the main compartment resulting in a use-after-free after unwrapping the proxy.
 (CVE-2023-25735)

 - Module load requests that failed were not being checked as to whether or not they were cancelled causing a use-after-free in <code>ScriptLoadContext</code>. (CVE-2023-25739)

 - Mozilla: Incorrect code generation during JIT compilation (CVE-2023-25751)

 - Following a Garbage Collector compaction, weak maps may have been accessed before they were correctly traced. This resulted in memory corruption and a potentially exploitable crash. (CVE-2023-29535)

 - An attacker could cause the memory manager to incorrectly free a pointer that addresses attacker- controlled memory, resulting in an assertion, memory corruption, or a potentially exploitable crash.
 (CVE-2023-29536)

 - A wrong lowering instruction in the ARM64 Ion compiler resulted in a wrong optimization result.
 (CVE-2023-29548)

 - Mozilla developers Andrew Osmond, Sebastian Hengst, Andrew McCreight, and the Mozilla Fuzzing Team reported memory safety bugs present in Thunderbird 102.9. 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. (CVE-2023-29550)

 - A type checking bug would have led to invalid code being compiled. (CVE-2023-32211)

 - Mozilla developers and community members Gabriele Svelto, Andrew Osmond, Emily McDonough, Sebastian Hengst, Andrew McCreight and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 112 and Firefox ESR 102.10. 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. (CVE-2023-32215)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected libmozjs-102-0 and / or libmozjs-102-dev packages.
