CVSS v2.0

6.8

Medium

Base vector

AV:N/AC:M/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 init function in sfnt/ttsbit.c, which does not restrict the count value, leading to a potential denial of service due to integer overflow and out-of-bounds read. This could be exploited by remote attackers using a crafted embedded bitmap.

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 access to embedded bitmaps to minimize the risk of exploitation.
