Original advisory details:

 It was discovered that positional arguments to the printf() family
 of functions were not handled properly in the GNU C Library. An
 attacker could possibly use this to cause a stack-based buffer
 overflow, creating a denial of service or possibly execute arbitrary
 code. (CVE-2012-3404, CVE-2012-3405, CVE-2012-3406)

 It was discovered that multiple integer overflows existed in the
 strtod(), strtof() and strtold() functions in the GNU C Library. An
 attacker could possibly use this to trigger a stack-based buffer
 overflow, creating a denial of service or possibly execute arbitrary
 code. (CVE-2012-3480)");

  script_tag(name:"affected", value:"'glibc' package(s) on Ubuntu 8.04.");

  script_tag(name:"solution", value:"Please install the updated package(s).");
