NewStart CGSL MAIN 6.02 : glibc Multiple Vulnerabilities (NS-SA-2021-0053)

The remote NewStart CGSL host, running version MAIN 6.02, has glibc packages installed that are affected by multiple vulnerabilities: - The idnatoascii4i function in lib/idna.c in libidn before 1.33 allows context-dependent attackers to cause a denial of service out-of-bounds read and crash via 6...

Medium: glibc

Issue Overview: stdlib/canonicalize.c in the GNU C Library aka glibc or libc6 2.27 and earlier, when processing very long pathname arguments to the realpath function, could encounter an integer overflow on 32-bit architectures, leading to a stack-based buffer overflow and, potentially, arbitrary...

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...
