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.
Affected configurations
• gnu glibc (<= 2.24)
• opensuse opensuse 13.2
• fedoraproject fedora 23
• fedoraproject fedora 24
• fedoraproject fedora 25
