Description
A stack buffer overflow flaw was found in the gsl package due to a lack of validation of the user controlled fraction parameter. This issue may allow an attacker to craft malicious input, leading to a segmentation fault and further Denial of Service. Since the buffer overflow happens when reading data from the input array, it's very unlikely to achieve arbitrary code execution using this flaw.
