1) Resource management error (CVE-ID: CVE-2011-1071)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
The GNU C Library (aka glibc or libc6) before 2.12.2 and Embedded GLIBC (EGLIBC) allow context-dependent attackers to execute arbitrary code or cause a denial of service (memory consumption) via a long UTF8 string that is used in an fnmatch call, aka a "stack extension attack," a related issue to CVE-2010-2898, CVE-2010-1917, and CVE-2007-4782, as originally reported for use of this library by Google Chrome.
