Dist Opensuse Esm H88
OpenSUSE faces security issues with glibc that demand urgent fixes. Key vulnerabilities and their solutions include buffer overflow, memory corruption, and stack overflow
An update that solves three vulnerabilities and has two fixes is now available.

Description

This update for glibc fixes the following security issues:

- CVE-2017-18269: An SSE2-optimized memmove implementation for i386 did

not correctly perform the overlapping memory check if the source memory

range spaned the middle of the address space, resulting in corrupt data

being produced by the copy operation. This may have disclosed

information to context-dependent attackers, resulted in a denial of

service or code execution (bsc#1094150).

- CVE-2018-11236: Prevent integer overflow on 32-bit architectures when

processing very long pathname arguments to the realpath function,

leading to a stack-based buffer overflow (bsc#1094161).

- CVE-2018-11237: An AVX-512-optimized implementation of the mempcpy

function may have writen data beyond the target buffer, leading to a

buffer overflow in __mempcpy_avx512_no_vzeroupper (bsc#1092877,

bsc#1094154).

This update was imported from the SUSE:SLE-15:Update update project.
