CVE-2010-4756 describes a denial-of-service vulnerability in the GNU C Library (glibc) glob implementation, affecting systems using glibc. Authenticated remote attackers can exploit this by submitting crafted glob expressions that do not match any pathnames, leading to high CPU and memory consumption. With a CVSS score of 4.0 (AV:N/AC:L/Au:S/C:N/I:N/A:P), it is considered a low-severity issue, requiring authentication and causing only availability impact. There is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this vulnerability.

The glob implementation in the GNU C Library (aka glibc or libc6) allows remote authenticated users to cause a denial of service (CPU and memory consumption) via crafted glob expressions that do not match any pathnames, as demonstrated by glob expressions in STAT commands to an FTP daemon, a different vulnerability than CVE-2010-2632.
