CVE-2017-18269

An SSE2-optimized memmove implementation for i386 in sysdeps/i386/i686/multiarch/memcpy-sse2-unaligned.S in the GNU C Library aka glibc or libc6 2.21 through 2.27 does not correctly perform the overlapping memory check if the source memory range spans the middle of the address space, resulting in...

CVE-2018-11237

An AVX-512-optimized implementation of the mempcpy function in the GNU C Library aka glibc or libc6 2.27 and earlier may write data beyond the target buffer, leading to a buffer overflow in mempcpyavx512novzeroupper...

CVE-2017-18269

CVE-2017-18269 affects glibc (memcpy-sse2-unaligned on i386) where the overlapping memory check can fail when the source spans the middle of the address space, producing data corruption that may lead to information disclosure, DoS, or potentially code execution. Affected versions: glibc 2.21–2.27...

CVE-2018-11236

Summary (CVE-2018-11236) : In glibc, the realpath path processing path can trigger an integer overflow in 32-bit builds within stdlib/canonicalize.c when handling very long pathname arguments, producing a stack-based buffer overflow and potentially arbitrary code execution. The vulnerability affe...
