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)
