Overview
solana_rbpf is a virtual machine for eBPF program execution
Affected versions of this package are vulnerable to Buffer Overflow via the function relocate in the file src/elf.rs. The integer overflow stems from the sym.st_value which is read directly from ELF file without checking. If the sym.st_value is large, it triggers the overflow while calculating the variable addr via addr = (sym.st_value + refd_pa) as u64;.
