OESA-2025-1265 — firefox security update

Affected: openEuler:22.03-LTS-SP4: firefox

Mozilla Firefox is a standalone web browser, designed for standards compliance and performance. Its functionality can be enhanced via a plethora of extensions. Security Fix(es):

When loading a script with Subresource Integrity, attackers with an injection capability could trigger the reuse of previously cached entries with incorrect, different integrity metadata. This vulnerability affects Firefox < 103.(CVE-2022-36315)

When using the Performance API, an attacker was able to notice subtle differences between PerformanceEntries and thus learn whether the target URL had been subject to a redirect. This vulnerability affects Firefox < 103.(CVE-2022-36316)

An attacker could have written a value to the first element in a zero-length JavaScript array. Although the array was zero-length, the value was not written to an invalid memory address. This vulnerability affects Firefox < 104.(CVE-2022-38475)

Service Workers did not detect Private Browsing Mode correctly in all cases, which could have led to Service Workers being written to disk for websites visited in Private Browsing Mode. This would not have persisted them in a state where they would run again, but it would have leaked Private Browsing Mode details to disk. This vulnerability affects Firefox < 107.(CVE-2022-45417)

If the user added a security exception for an invalid TLS certificate, opened an ongoing TLS connection with a server that used that certificate, and then deleted the exception, Firefox woul…
