Updated firefox packages fix security vulnerability

Updated firefox and libwebp packages fix security vulnerabilities:

Unexpected data returned from the Safe Browsing API could have led to memory

corruption and a potentially exploitable crash (CVE-2023-1945).

A website could have obscured the fullscreen notification by using a

combination of window.open, fullscreen requests, window.name assignments, and

setInterval calls. This could have led to user confusion and possible spoofing

attacks (CVE-2023-29533).

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, via JavaScript code, 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).

When handling the filename directive in the Content-Disposition header, the

filename would be truncated if the filename contained a NULL character. This

could have led to reflected file download attacks potentially tricking users

to install malware (CVE-2023-29539).

Firefox did not properly handle downloads of files ending in .desktop, which

can be interpreted to run attacker-controlled commands (CVE-2023-29541).

Mozilla developers Andrew Osmond, Sebastian Hengst, Andrew McCreight, and the

Mozilla Fuzzing Team reported memory safety bugs present in Firefox ESR 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 double-free in libwebp could have led to memory corruption and a

potentially exploitable crash (MFSA-TMP-2023-0001).
