critical Nessus Plugin ID 187937

Language:

Synopsis

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

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS / 23.04 / 23.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6574-1 advisory.

 Takeshi Kaneko discovered that Go did not properly handle comments and special tags in the script context of html/template module. An attacker could possibly use this issue to inject Javascript code and perform a cross site scripting attack. This issue only affected Go 1.20 in Ubuntu 20.04 LTS, Ubuntu 22.04 LTS and Ubuntu 23.04. (CVE-2023-39318, CVE-2023-39319)

 It was discovered that Go did not properly validate the //go:cgo_ directives during compilation. An attacker could possibly use this issue to inject arbitrary code during compile time. (CVE-2023-39323)

 It was discovered that Go did not limit the number of simultaneously executing handler goroutines in the net/http module. An attacker could possibly use this issue to cause a panic resulting into a denial of service. (CVE-2023-39325, CVE-2023-44487)

 It was discovered that the Go net/http module did not properly validate the chunk extensions reading from a request or response body. An attacker could possibly use this issue to read sensitive information.
 (CVE-2023-39326)

 It was discovered that Go did not properly validate the insecure git:// protocol when using go get to fetch a module with the .git suffix. An attacker could possibly use this issue to bypass secure protocol checks. (CVE-2023-45285)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution
