Debian Linux Security Advisory 3012-1 - 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.

Package : eglibc
CVE ID : 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.

For the stable distribution (wheezy), this problem has been fixed in
version 2.13-38+deb7u4.

We recommend that you upgrade your eglibc packages.
