openSUSE 15 Security Update : MozillaFirefox (openSUSE-SU-2021:2393-1)

high Nessus Plugin ID 151820

Language:

Synopsis

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

Description

The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2021:2393-1 advisory.

- A malicious webpage could have triggered a use-after-free, memory corruption, and a potentially exploitable crash. This bug only affected Firefox when accessibility was enabled. (CVE-2021-29970)

- Mozilla developers Emil Ghitta, Tyson Smith, Valentin Gosu, Olli Pettay, and Randell Jesup reported memory safety bugs present in Firefox 89 and Firefox ESR 78.11. 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-2021-29976)

- Out of bounds write in ANGLE in Google Chrome prior to 91.0.4472.101 allowed a remote attacker to potentially perform out of bounds memory access via a crafted HTML page. (CVE-2021-30547)

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

Solution

Update the affected packages.
