Title

powerpc和Intel i386 GNU C Library整数溢出漏洞

Description

powerpc是一种精简指令集架构的CPU（中央处理器）。Intel i386是美国英特尔（Intel）公司的一款x86系列CPU（中央处理器）。GNU C Library（又名glibc，libc6）是其中的一套按照LGPL许可协议发布的开源免费的C语言编译程序。 powerpc上的GNU C Library 2.24版本至2.26版本和Intel i386上的GNU C Library 2.26版本中的malloc实现存在整数溢出漏洞，该漏洞源于程序未能正确的处理malloc调用，并向堆区域回复较小的指针。攻击者可利用该漏洞造成堆损坏。

CVE-2018-6551 (GCVE-0-2018-6551)

Vulnerability from cvelistv5 – Published: 2018-02-02 14:00 – Updated: 2024-08-05 06:10

Summary

The malloc implementation in the GNU C Library (aka glibc or libc6), from version 2.24 to 2.26 on powerpc, and only in version 2.26 on i386, did not properly handle malloc calls with arguments close to SIZE_MAX and could return a pointer to a heap region that is smaller than requested, eventually leading to heap corruption.

Severity

No CVSS data available.
