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.
Andreas Schwab discovered that the GNU C Library on ARM 32-bit
platforms did not properly set up execution contexts. An attacker
could use this to cause a denial of service.
