Version : 2.5+dfsg-6+deb10u1
CVE ID : CVE-2020-35357

A buffer overflow can occur when calculating the quantile value using the
Statistics Library of GSL (GNU Scientific Library). 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.

For Debian 10 buster, this problem has been fixed in version
2.5+dfsg-6+deb10u1.

We recommend that you upgrade your gsl packages.
