CVE-2020-35357 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. 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.. EPSS estimates a 0.88% chance of exploitation in the next 30 days.
