openSUSE Security Update: Security update for glibc ______________________________________________________________________________ Announcement ID: openSUSE-SU-2018:2159-1 Rating: moderate References: #1082318 #1092877 #1094150 #1094154 #1094161 Cross-References: CVE-2017-18269 CVE-2018-11236 CVE-2018-11237 Affected Products: openSUSE Leap 15.0 ______________________________________________________________________________ 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.
