| 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. 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.
