Detailsinfo

A vulnerability, which was classified as critical, has been found in GNU Scientific Library 2.5/2.6 (Software Library). This issue affects the function gsl_stats_quantile_from_sorted_data of the component Statistics Library. The manipulation of the argument quantile with an unknown input leads to a buffer overflow vulnerability. Using CWE to declare the problem leads to CWE-120. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

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.

The weakness was published 08/23/2023. The advisory is shared at git.savannah.gnu.org. The identification of this vulnerability is CVE-2020-35357 since 12/14/2020. Technical details are known, but no exploit is available.

The vulnerability scanner Nessus provides a plugin with the ID 212154 (Debian dla-3985 : gsl-bin - security update), which helps to determine the existence of the flaw in a target environment.

Applying a patch is able to eliminate this problem. The bugfix is ready for download at git.savannah.gnu.org.
