AFFECTSRootCause

readlink() does not NUL-terminate, and the code treats a full-length result as success without writing a terminator. Tension: The buffer is not NUL-terminated before any later string use. Outcome: buffer contents depend on whatever stack bytes follow the copied link data.

PERTAIN_TOProblem

If size_t arithmetic overflows — glibc's timezone compiler (zic.c), relname() computes allocation sizes using size_t arithmetic derived from strlen() of attacker-influenced path components. Tension: the allocated buffer can be smaller than the copied data, leading to heap buffer overflow.
