Hello Linux users,
Thunderbird is back in the spotlight today as threat actors exploit recent vulnerabilities in the open-source email client to access sensitive data and disrupt services of critical Linux systems with denial-of-service attacks. The article I link to here contains the technical details you may want to know about these severe bugs.
Read on to learn how to mitigate these flaws and find out about other impactful vulnerabilities recently identified and fixed in your open-source programs and applications.

Stay safe out there,
ThunderbirdThe DiscoverySeveral severe vulnerabilities have been discovered in Thunderbird. A malicious actor could exploit these bugs to launch a denial of service attack, steal sensitive data, bypass security restrictions, perform cross-site tracing, or execute arbitrary code. |
FirefoxThe DiscoveryFirefox users are also at risk this week, as important memory safety bugs have been found in the widely used web browser. Some of these bugs have shown evidence of memory corruption and could have been exploited to run arbitrary code. |
X.OrgThe DiscoveryHave you updated to mitigate the severe security vulnerabilities recently discovered in the X.Org server before 21.1.11 and Xwayland display implementations before 23.2.4? These security flaws could result in heap overflows, out-of-bounds writes, and privilege escalation, enabling attackers to view additional infrastructure to attack, add or delete users, or modify permissions of files or other users. The initial fix for these vulnerabilities was found to be incomplete, resulting in a possible regression. |
