CVE-2013-4237: Buffer Overflow
First published: Sun Aug 11 2013(Updated: )
An out-of buffer bounds write flaw was found in the way the readdir_r function in glibc, the GNU C Library, handled a directory entry whose file name name contained more byte than the NAME_MAX characters constant indicated. An attacker could provide a specially-crafted (local) NTFS or (remote) CIFS file system that, when processed in an application using the readdir_r() function, would cause that application to crash or, potentially, execute arbitrary code with the privileges of the user running the application.
