"CVE-2014-0475

Stephane Chazelas discovered that the GNU C library, glibc, processed
'..' path segments in locale-related environment variables, possibly
allowing attackers to circumvent intended restrictions, such as
ForceCommand in OpenSSH, assuming that they can supply crafted locale
settings.

CVE-2014-5119

Tavis Ormandy discovered a heap-based buffer overflow in the
transliteration module loading code in eglibc, Debian's version of the
GNU C Library. As a result, an attacker who can supply a crafted
destination character set argument to iconv-related character
conversation functions could achieve arbitrary code execution.

This update removes support of loadable gconv
transliteration modules. Besides the security vulnerability,
the module loading code had functionality defects which
prevented it from working for the intended purpose.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
