7.5

High

Base vector

AV:N/AC:L/Au:N/C:P/I:P/A:P

Name of the Vulnerable Software and Affected Versions FreeType versions prior to 2.5.4

Description The issue is related to the tt sbit decoder load image function in sfnt/ttsbit.c, which does not properly check for an integer overflow. This allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have other unspecified impacts via a crafted OpenType font.

Recommendations For versions prior to 2.5.4, update to version 2.5.4 or later to resolve the issue. As a temporary workaround, consider restricting the use of crafted OpenType fonts to minimize the risk of exploitation.
