Security Fix(es):

Multiple NSS NIST curves were susceptible to a side-channel attack known as "Minerva". This attack could potentially allow an attacker to recover the private key. This vulnerability affects Firefox < 121.(CVE-2023-6135)

Ownership mismanagement led to a use-after-free in ReadableByteStreams This vulnerability affects Firefox < 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5.(CVE-2023-6207)

When using X11, text selected by the page using the Selection API was erroneously copied into the primary selection, a temporary storage not unlike the clipboard. This bug only affects Firefox on X11. Other systems are unaffected. This vulnerability affects Firefox < 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5.(CVE-2023-6208)

Relative URLs starting with three slashes were incorrectly parsed, and a path-traversal "/../" part in the path could be used to override the specified host. This could contribute to security problems in web sites. This vulnerability affects Firefox < 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5.(CVE-2023-6209)

When an https: web page created a pop-up from a "javascript:" URL, that pop-up was incorrectly allowed to load blockable content such as iframes from insecure http: URLs This vulnerability affects Firefox < 120.(CVE-2023-6210)

If an attacker needed a user to load an insecure http: page and knew that user had enabled HTTPS-only mode, the attacker could have tricked the user into clicking to grant an HTTPS-only exception if they could get the user to participate in a clicking game. This vulnerability affects Firefox < 120.(CVE-2023-6211)

Memory safety bugs present in Firefox 119, Firefox ESR 115.4, and Thunderbird 115.4. 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. This vulnerability affects Firefox < 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5.(CVE-2023-6212)

Memory safety bugs present in Firefox 119. 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. This vulnerability affects Firefox < 120.(CVE-2023-6213)

The WebGL DrawElementsInstanced method was susceptible to a heap buffer overflow when used on systems with the Mesa VM driver.

Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information across domains, or execute arbitrary code.(CVE-2023-6865, CVE-2023-6857, CVE-2023-6858, CVE-2023-6859, CVE-2023-6866, CVE-2023-6867, CVE-2023-6861, CVE-2023-6869, CVE-2023-6871, CVE-2023-6872, CVE-2023-6863, CVE-2023-6864, CVE-2023-6873)

George Pantela and Hubert Kario discovered that Firefox using multiple NSS NIST curves which were susceptible to a side-channel attack known as "Minerva". An attacker could potentially exploit this issue to obtain sensitive information. (CVE-2023-6135)

Andrew Osmond discovered that Firefox did not properly validate the textures produced by remote decoders. An attacker could potentially exploit this issue to escape the sandbox. (CVE-2023-6860)

It was discovered that NSS incorrectly handled padding when checking PKCS#1 certificates. A remote attacker could possibly use this issue to perform Bleichenbacher-like attacks and recover private data. This issue only affected Ubuntu 20.04 LTS. (CVE-2023-4421)

It was discovered that NSS had a timing side-channel when performing RSA decryption. A remote attacker could possibly use this issue to recover private data. (CVE-2023-5388)

It was discovered that NSS had a timing side-channel when using certain NIST curves. A remote attacker could possibly use this issue to recover private data. (CVE-2023-6135)

The NSS package contained outdated CA certificates. This update refreshes the NSS package to version 3.98 which includes the latest CA certificate bundle and other security improvements.
