Descriptions

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.

La función makecontext en GNU C Library (también conocido como glibc o libc6) en versiones anteriores a 2.25 crea contexto de ejecución incompatibles con el desbobinador en plataformas ARM EABI (32-bit), lo que podría permitir a atacantes dependientes del contexto provocar una denegación de servicio (cuelgue), según lo demostrado por las aplicaciones compiladas utilizando gccgo, relacionado con la generación de traza inversa.
