CVSS v3.1
Official 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
Technical Analysis
CVE-2007-3508 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
