CVE-2016-6323

HIGH

glibc < 2.25 - Denial of Service via makecontext Function

Title source: llm
STIX 2.1

Description

The makecontext function in the GNU C Library (aka glibc or libc6) before 2.25 creates execution contexts incompatible with the unwinder on ARM EABI (32-bit) platforms, which might allow context-dependent attackers to cause a denial of service (hang), as demonstrated by applications compiled using gccgo, related to backtrace generation.
