#CVE-2023-28176: Memory safety bugs fixed in Thunderbird 102.9
Reporter:Mozilla developers and community
Impact:high
Description
Mozilla developers Timothy Nikkel, Andrew McCreight, and the Mozilla Fuzzing Team reported memory safety bugs present in Thunderbird 102.8. 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.

Interessiert in verschiedenste IT Themen, schreibe ich in diesem Blog über Software, Hardware, Smart Home, Games und vieles mehr. Ich berichte z.B. über die Installation und Konfiguration von Software als auch von Problemen mit dieser. News sind ebenso spannend, sodass ich auch über Updates, Releases und Neuigkeiten aus der IT berichte. Letztendlich nutze ich Taste-of-IT als eigene Dokumentation und Anlaufstelle bei wiederkehrenden Themen. Ich hoffe ich kann dich ebenso informieren und bei Problemen eine schnelle Lösung anbieten. Wer meinen Aufwand unterstützen möchte, kann gerne eine Tasse oder Pod Kaffe per PayPal spenden – vielen Dank.
