JVN/CVE Demo: Cveinfos

CVE

Id: 104712
CVE No.: CVE-2017-7892
Status: Candidate
Description: 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.
Phase: Assigned (20170417)
Votes: None (candidate not yet proposed)
