Test ID:1.3.6.1.4.1.25623.1.1.10.2017.0394
Category:Mageia Linux Local Security Checks
Title:Mageia: Security Advisory (MGASA-2017-0394)
Summary:The remote host is missing an update for the 'rpm' package(s) announced via the MGASA-2017-0394 advisory.
Description:Summary:
The remote host is missing an update for the 'rpm' package(s) announced via the MGASA-2017-0394 advisory.

Vulnerability Insight:
It was found that rpm did not properly handle RPM installations when a
destination path was a symbolic link to a directory, possibly changing
ownership and permissions of an arbitrary directory, and RPM files being
placed in an arbitrary destination. An attacker, with write access to a
directory in which a subdirectory will be installed, could redirect that
directory to an arbitrary location and gain root privilege
(CVE-2017-7500).

It was found that rpm uses temporary files with predictable names when
installing an RPM. An attacker with ability to write in a directory
where files will be installed could create symbolic links to an
arbitrary location and modify content, and possibly permissions to
arbitrary files, which could be used for denial of service or possibly
privilege escalation (CVE-2017-7501)

Affected Software/OS:
'rpm' package(s) on Mageia 6.

Solution:
Please install the updated package(s).

CVSS Score:
