Medium Nessus Plugin ID 135165

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 6.7

Synopsis

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

Description

This update for glibc fixes the following issues :

CVE-2020-1752: Fixed a use after free in glob which could have allowed a local attacker to create a specially crafted path that, when processed by the glob function, could potentially have led to arbitrary code execution (bsc#1167631).

CVE-2020-1751: Fixed an array overflow in backtrace for PowerPC (bsc#1158996).

CVE-2020-10029: Fixed a stack-based buffer overflow during range reduction (bsc#1165784).

Use 'posix_spawn' on popen preventing crash caused by 'subprocess'.
(bsc#1149332, BZ #22834)

Fix handling of needles crossing a page, preventing incorrect results to return during the cross page boundary search. (bsc#1157893, BZ #25226)

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.
