Ubuntu 20.04 LTS : Firefox vulnerabilities (USN-7263-1)

critical Nessus Plugin ID 216055

Synopsis

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

Description

The remote Ubuntu 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7263-1 advisory.

 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-2025-1011, CVE-2025-1013, CVE-2025-1014, CVE-2025-1016, CVE-2025-1017, CVE-2025-1018, CVE-2025-1019, CVE-2025-1020)

 Ivan Fratric discovered that Firefox did not properly handle XSLT data, leading to a use-after-free vulnerability. An attacker could potentially exploit this issue to cause a denial of service, or execute arbitrary code. (CVE-2025-1009)

 Atte Kettunen discovered that Firefox did not properly manage memory in the Custom Highlight API, leading to a use-after-free vulnerability. An attacker could potentially exploit this issue to cause a denial of service, or execute arbitrary code. (CVE-2025-1010)

 Nils Bars discovered that Firefox did not properly manage memory during concurrent delazification, leading to a use-after-free vulnerability. An attacker could potentially exploit this issue to cause a denial of service, or execute arbitrary code. (CVE-2025-1012)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

Solution

Update the affected packages.
