Descriptions

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.st_value is read directly from ELF file without checking. If the sym.st_value is rather large, an integer overflow is triggered while calculating the variable "addr" via "addr = (sym.st_value + refd_pa) as u64";

De la versión 0.2.14 a 0.2.16 para Solana rBPF, la función "relocate" en el archivo src/elf.rs presenta un bug de desbordamiento de enteros porque el sym.st_value es leído directamente del archivo ELF sin comprobarlo. Si el sym.st_value es bastante grande, es producido un desbordamiento de enteros mientras es calculada la variable "addr" por medio de "addr = (sym.st_value + refd_pa) as u64"
