GHSA-Q5JR-PH84-C3R5

Vulnerability from github – Published: 2022-05-17 02:48 – Updated: 2022-05-17 02:48

Details

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.

Severity ?

7.5 (High)
