Updated dpkg packages fix security vulnerabilities

Publication date: 11 Jul 2025
Modification date: 11 Jul 2025
Type: security
Affected Mageia releases : 9
CVE: CVE-2025-6297

Description

It was discovered that dpkg-deb does not properly sanitize directory
permissions when extracting a control member into a temporary directory,
which is documented as being a safe operation even on untrusted data.
This may result in leaving temporary files behind on cleanup. Given
automated and repeated execution of dpkg-deb commands on adversarial
.deb packages or with well compressible files, placed inside a directory
with permissions not allowing removal by a non-root user, this can end
up in a DoS scenario due to causing disk quota exhaustion or disk full
conditions.
