From version 0.2.14 to 0.2.16 for Solana rBPF, function "relocate" in the file src/elf.rs has an integer overflow bug because the sym.stvalue is read directly from ELF file without checking. If the sym.stvalue is rather large, an integer overflow is triggered while calculating the variable "addr" via "addr = (sym.stvalue + refdpa) as u64";

Solana solanarbpf before 0.2.29 has an addition integer overflow via invalid ELF program headers. elf.rs has a panic via a malformed eBPF program.

Solana Pay is a protocol and set of reference implementations that enable developers to incorporate decentralized payments into their apps and services. When a Solana Pay transaction is located using a reference key, it may be checked to represent a transfer of the desired amount to the recipient, using the supplied validateTransfer function. An edge case regarding this mechanism could cause the validation logic to validate multiple transfers. This issue has been patched as of version 0.2.1. Users of the Solana Pay SDK should upgrade to it. There are no known workarounds for this issue.
