Title: FreeType 2堆缓冲区溢出漏洞

Description:

FreeType2是FreeType团队开发的一个基于C语言的、可移植的开源字体引擎库，它可用来将字符栅格化并映射成位图以及提供其他字体相关业务的支持。

FreeType 2 2.7之前版本中的type1/t1load.c文件的parse_charstrings函数存在堆缓冲区溢出漏洞，该漏洞源于程序未能确定字体中是否带有标志符号名称。远程攻击者可借助特制的文件利用该漏洞造成拒绝服务（越边界读取）。

CVE-2016-10244 (GCVE-0-2016-10244)

Vulnerability from cvelistv5

Published

Modified

2024-08-06 03:14

Severity ?

CWE

Summary

The parse_charstrings function in type1/t1load.c in FreeType 2 before 2.7 does not ensure that a font contains a glyph name, which allows remote attackers to cause a denial of service (heap-based buffer over-read) or possibly have unspecified other impact via a crafted file.
