nsViewManager.cpp in Mozilla Firefox 3.0.2 through 3.0.10 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via vectors related to interaction with TinyMCE.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
