The remote host was detected running an outdated version of Pale Moon.
Versions of Pale Moon browser earlier than 24.3.2 are outdated and thus unpatched for a buffer overflow. A flaw exists in the function 'cairo_dwrite_load_truetype_table()' in 'cairo-dwrite-font.cpp' that is triggered as user-supplied input is not properly validated. This may allow a context-dependent attacker to trigger a buffer overflow, resulting in a denial of service or potentially allowing the execution of arbitrary code.
Upgrade to Pale Moon browser version 24.3.2, or later.
