Title: GNU C Library分段错误漏洞

Description:

GNU C Library (glibc)是一种按照LGPL许可协议发布的、开源、免费、方便从网络下载的C的编译程序。

GNU C Library 2.28及更早版本存在分段错误漏洞。该漏洞源于当在x32架构上运行时，GNU C Library中的string组件错误地尝试在汇编代码中为size_t使用64位寄存器。攻击者可利用该漏洞导致拒绝服务。

Severity: 中

Summary

The string component in the GNU C Library (aka glibc or libc6) through 2.28, when running on the x32 architecture, incorrectly attempts to use a 64-bit register for size_t in assembly codes, which can lead to a segmentation fault or possibly unspecified other impact, as demonstrated by a crash in __memmove_avx_unaligned_erms in sysdeps/x86_64/multiarch/memmove-vec-unaligned-erms.S during a memcpy.
