(CVE-2014-9761) * It was found that out-of-range time values passed to the strftime() function could result in an out-of-bounds memory access. This could lead to application crash or, potentially, information disclosure. (CVE-2015-8776) * An integer overflow vulnerability was found in hcreate() and hcreate_r() functions which could result in an out-of-bounds memory access. This could lead to application crash or, potentially, arbitrary code execution. (CVE-2015-8778) * A stack based buffer overflow vulnerability was found in the catopen() function.
