CVE-2017-7892

https://notcve.org/view.php?id=CVE-2017-7892

Sandstorm Cap'n Proto before 0.5.3.1 allows remote crashes related to a compiler optimization. A remote attacker can trigger a segfault in a 32-bit libcapnp application because Cap'n Proto relies on pointer arithmetic calculations that overflow. An example compiler with optimization that elides a bounds check in such calculations is Apple LLVM version 8.1.0 (clang-802.0.41). The attack vector is a crafted far pointer within a message. Sandstorm Cap'n Proto en versiones anteriores a 0.5.3.1 permite bloqueos a distancia relacionados con una optimización del compilador. • https://github.com/sandstorm-io/capnproto/blob/master/security-advisories/2017-04-17-0-apple-clang-elides-bounds-check.md • CWE-20: Improper Input Validation •
