SUSE SLED12 / SLES12 Security Update : rpm (SUSE-SU-2018:3884-1)

high Nessus Plugin ID 119145

Language:

Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update for rpm fixes the following issues :

These security issues were fixed :

CVE-2017-7500: 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 (bsc#943457).

CVE-2017-7501: rpm used 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 (bsc#943457)

This is a reissue of the above security fixes for SUSE Linux Enterprise 12 GA, SP1 and SP2 LTSS, they have already been released for SUSE Linux Enterprise Server 12 SP3.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
