glibc ELF code execution

glibc-elf-code-execution (58915) The risk level is classified as HighHigh Risk

Description:

glibc could allow a remote attacker to execute arbitrary code on the system, caused by an integer overflow error in ld.so. By persuading a victim to process a specially-crafted ELF binary, an attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service.
