#CVE-2023-4573: Memory corruption in IPC CanvasTranslator

Reporter sonakkbi
Impact high
Description

When receiving rendering data over IPC mStream could have been destroyed when initialized, which could have led to a use-after-free causing a potentially exploitable crash.

#CVE-2023-4574: Memory corruption in IPC ColorPickerShownCallback

Reporter sonakkbi
Impact high
Description

When creating a callback over IPC for showing the Color Picker window, multiple of the same callbacks could have been created at a time and eventually all simultaneously destroyed as soon as one of the callbacks finished. This could have led to a use-after-free causing a potentially exploitable crash.

Description

When creating a callback over IPC for showing the File Picker window, multiple of the same callbacks could have been created at a time and eventually all simultaneously destroyed as soon as one of the callbacks finished.

#CVE-2023-4576: Integer Overflow in RecordedSourceSurfaceCreation

Reporter fffvr
Impact high
Description

On Windows, an integer overflow could occur in RecordedSourceSurfaceCreation which resulted in a heap buffer overflow potentially leaking sensitive data that could have led to a sandbox escape.
This bug only affects Firefox on Windows. Other operating systems are unaffected.

#CVE-2023-4577: Memory corruption in JIT UpdateRegExpStatics

Reporter Lukas Bernhard
Impact high
Description

When UpdateRegExpStatics attempted to access initialStringHeap it could already have been garbage collected prior to entering the function, which could potentially have led to an exploitable crash.

#CVE-2023-4051: Full screen notification obscured by file open dialog

Reporter Hafiizh
Impact moderate
Description

A website could have obscured the full screen notification by using the file open dialog. This could have led to user confusion and possible spoofing attacks.

References

#CVE-2023-4578: Error reporting methods in SpiderMonkey could have triggered an Out of Memory Exception

Reporter Irvan Kurniawan (@sourc7)
Impact moderate
Description

When calling JS::CheckRegExpSyntax a Syntax Error could have been set which would end in calling convertToRuntimeErrorAndClear. A path in the function could attempt to allocate memory when none is available which would have caused a newly created Out of Memory exception to be mishandled as a Syntax Error.

#CVE-2023-4053: Full screen notification obscured by external program

Reporter Umar Farooq
Impact moderate
Description

A website could have obscured the full screen notification by using a URL with a scheme handled by an external program, such as a mailto URL. This could have led to user confusion and possible spoofing attacks.

References

#CVE-2023-4580: Push notifications saved to disk unencrypted

Reporter Harveer Singh
Impact moderate
Description

Push notifications stored on disk in private browsing mode were not being encrypted potentially allowing the leak of sensitive information.

References

#CVE-2023-4581: XLL file extensions were downloadable without warnings

Reporter Umar Farooq (@Puf)
Impact moderate
Description

Excel .xll add-in files did not have a blocklist entry in Firefox's executable blocklist which allowed them to be downloaded without any warning of their potential harm.

#CVE-2023-4582: Buffer Overflow in WebGL glGetProgramiv

Reporter Dohyun Lee (@l33d0hyun) of SSD-Disclosure Labs & DNSLab, Korea Univ.
Impact low
Description

Due to large allocation checks in Angle for glsl shaders being too lenient a buffer overflow could have occured when allocating too much private shader memory on mac OS.
This bug only affects Firefox on macOS. Other operating systems are unaffected.

References

#CVE-2023-4583: Browsing Context potentially not cleared when closing Private Window

Reporter Thejaka Maldeniya
Impact low
Description

When checking if the Browsing Context had been discarded in HttpBaseChannel, if the load group was not available then it was assumed to have already been discarded which was not always the case for private channels after the private session had ended.

#CVE-2023-4584: Memory safety bugs fixed in Firefox 117, Firefox ESR 102.15, Firefox ESR 115.2, Thunderbird 102.15, and Thunderbird 115.2

Reporter Randell Jesup, Andrew McCreight, the Mozilla Fuzzing Team
Impact high
Description

Memory safety bugs present in Firefox 116, Firefox ESR 102.14, Firefox ESR 115.1, Thunderbird 102.14, and Thunderbird 115.1. 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.

ff v117.0.1

12. sep 2023

Fixed

  • Fixed a bug causing links opened from outside Firefox to not open on macOS (bug 1850828)

  • Fixed a bug causing extensions using an event page for long-running tasks to be terminated while running, causing unexpected behavior changes (bug 1851373)

  • Temporarily reverted an intentional behavior change preventing Javascript from changing URL.protocol (bug 1850954).
    NOTE: This change is expected to ship in a later Firefox release alongside other web browsers and sites are encouraged to find alternate ways to change the protocol if needed.

  • Fixed audio worklets not working for sites using WebAssembly exception handling (bug 1851468)

  • Fixed the Reopen all tabs option in the Recently closed tabs menu sometimes failing to open all tabs (bug 1850856)

  • Fixed the bookmarks menu sometimes remaining partially visible when minimizing Firefox (bug 1843700)

  • Fixed an issue causing incorrect time zones to be detected on some sites (bug 1848615)

  • Security fix
