A recently discovered flaw in KDE KGet presents an opportunity for malicious actors to replace user files through specially designed metalink documents on various Ubuntu versions.
An attacker could overwrite files owned by the user if KGet opened a crafted metalink file.

Summary

An attacker could overwrite files owned by the user if KGet opened a

crafted metalink file.

Software Description:

- kdenetwork: networking applications for KDE 4

Details:

It was discovered that KGet did not properly perform input validation when

processing metalink files. If a user were tricked into opening a crafted

metalink file, a remote attacker could overwrite files via directory

traversal, which could eventually lead to arbitrary code execution.
