GHSA-g54x-7hpm-29q8 · 深刻度: high — In OCaml before 4.14.3 and 5.x before 5.4.1, a buffer over-read in Marshal deserialization ...
In OCaml before 4.14.3 and 5.x before 5.4.1, a buffer over-read in Marshal deserialization (runtime/intern.c) enables remote code execution through a multi-phase attack chain. The vulnerability stems from missing bounds validation in the readblock() function, which performs unbounded memcpy() operations using attacker-controlled lengths from crafted Marshal data.
