==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

Summary:

GNU C Library could be made to crash or run programs if it processed
specially crafted data.

Software Description:
- glibc: GNU C Library

Details:

Charles Fol discovered that the GNU C Library iconv feature incorrectly
handled certain input sequences. An attacker could use this issue to cause
the GNU C Library to crash, resulting in a denial of service, or possibly
execute arbitrary code.
