ubuntu
Calendar Grey November 7, 2023
Dist Ubuntu Esm H88
The recent GSL vulnerability poses a risk to Ubuntu LTS platforms, possibly enabling malicious actors to run arbitrary code or trigger system failures.
GNU Scientific Library could be made to crash or execute arbitrary code if it received specially crafted input.

Summary

GNU Scientific Library could be made to crash or execute arbitrary code if it

received specially crafted input.

Software Description:

- gsl: A modern numerical library for C and C++ programmers

Details:

It was discovered that GNU Scientific Library incorrectly handled certain

inputs. If a user or an automated system were tricked into opening a specially

crafted input file, a remote attacker could possibly use this issue to cause a

denial of service or execute arbitrary code.
