VetorAV:N/AC:L/Au:N/C:C/I:C/A:C
Name of the Vulnerable Software and Affected Versions Mozilla Firefox versions prior to 43.0
Description The issue is caused by a buffer overflow in the DirectWriteFontInfo::LoadFontFamilyData function. This could allow a remote attacker to cause a denial of service or possibly have other unspecified impacts by using a specially crafted font-family name. The DirectWriteFontInfo::LoadFontFamilyData function in gfx/thebes/gfxDWriteFontList.cpp is the vulnerable component.
Recommendations For versions prior to 43.0, update to version 43.0 or later to resolve the issue. As a temporary workaround, consider restricting the use of the DirectWriteFontInfo::LoadFontFamilyData function until a patch is available. Avoid using specially crafted font-family names in the affected function to minimize the risk of exploitation.
