EulerOS 2.0 SP8 : ruby (EulerOS-SA-2020-1178)

high Nessus Plugin ID 134012

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the ruby packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- An issue was discovered in Oniguruma 6.x before 6.9.4_rc2. In the function fetch_interval_quantifier (formerly known as fetch_range_quantifier) in regparse.c, PFETCH is called without checking PEND.
This leads to a heap-based buffer over-read.(CVE-2019-19204)

- Oniguruma before 6.9.3 allows Stack Exhaustion in regcomp.c because of recursion in regparse.c.(CVE-2019-16163)

- Oniguruma through 6.9.3, as used in PHP 7.3.x and other products, has a heap-based buffer over-read in str_lower_case_match in regexec.c.(CVE-2019-19246)

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

Solution

Update the affected ruby packages.
