Amazon Linux 2023: CVE-2020-35357: Medium priority package update for gsl

A buffer overflow can occur when calculating the quantile value using the Statistics Library of GSL (GNU Scientific Library), versions 2.5 and 2.6. Processing a maliciously crafted input data for gsl_stats_quantile_from_sorted_data of the library may lead to unexpected application termination or arbitrary code execution.
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.
