Technical description

Integer overflow in the process_envvars function in elf/rtld.c in glibc before 2.5-rc4 might allow local users to execute arbitrary code via a large LD_HWCAP_MASK environment variable value. NOTE: the glibc maintainers state that they do not believe that this issue is exploitable for code execution

Remediation

Check the references section for vendor advisories and patches from gentoo. Update glibc to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
