Description

Apple Safari Technology Preview是美国苹果（Apple）公司的一款浏览器。WebKit是KDE社区开发的一套开源Web浏览器引擎，目前被Apple Safari及Google Chrome等浏览器使用。 Apple Safari Technology Preview Release 46版本中的WebKit的WTF/wtf/FastBitVector.h文件存在拒绝服务漏洞，该漏洞源于程序调用‘FastBitVectorWordOwner::resizeSlow’函数未能适用于初始化bitvector。远程攻击者可利用该漏洞造成拒接服务（缓冲区溢出）。

CVE-2017-17821 (GCVE-0-2017-17821)

Vulnerability from cvelistv5 – Published: 2017-12-21 03:00 – Updated: 2024-08-05 20:59

Summary

WTF/wtf/FastBitVector.h in WebKit, as distributed in Safari Technology Preview Release 46, allows remote attackers to cause a denial of service (buffer overflow) or possibly have unspecified other impact because it calls the FastBitVectorWordOwner::resizeSlow function (in WTF/wtf/FastBitVector.cpp) for a purpose other than initializing a bitvector size, and resizeSlow mishandles cases where the old array length is greater than the new array length.

Severity ?

No CVSS data available.
