(Get the code!)
An integer overflow, leading to buffer overflow flaw was found in the way the implementation of strcoll() routine, used to compare two strings based on the current locale, of glibc, the GNU libc libraries, performed calculation of memory requirements / allocation, needed for storage of the strings. If an application linked against glibc was missing an application-level sanity checks for validity of strcoll() arguments and accepted untrusted input, an attacker could use this flaw to cause the particular application to crash or, potentially, execute arbitrary code with the privileges of the user running the application.
