openSUSE: 2018:3373-1 Moderate: Denial Of Service And Escalation

opensuse
Calendar Grey October 24, 2018
Dist Opensuse Esm H88
This patch enhances the security framework in the rpm package for openSUSE, improving overall protection and stability.
An update that fixes two vulnerabilities is now available.

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 non-security issue was fixed:

- Use ksym-provides tool [bsc#1077692]

This update was imported from the SUSE:SLE-12:Update update project.
