EulerOS 2.0 SP5 : golang (EulerOS-SA-2024-1140)

high Nessus Plugin ID 190289

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

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

 - The HTTP/1 client does not fully validate the contents of the Host header. A maliciously crafted Host header can inject additional headers or entire requests. With fix, the HTTP/1 client now refuses to send requests containing an invalid Request.Host or Request.URL.Host value. (CVE-2023-29406)

 - Extremely large RSA keys in certificate chains can cause a client/server to expend significant CPU time verifying signatures. With fix, the size of RSA keys transmitted during handshakes is restricted to <= 8192 bits. Based on a survey of publicly trusted RSA keys, there are currently only three certificates in circulation with keys larger than this, and all three appear to be test certificates that are not actively deployed. It is possible there are larger keys in use in private PKIs, but we target the web PKI, so causing breakage here in the interests of increasing the default safety of users of crypto/tls seems reasonable. (CVE-2023-29409)

 - Line directives ('//line') can be used to bypass the restrictions on '//go:cgo_' directives, allowing blocked linker and compiler flags to be passed during compilation. This can result in unexpected execution of arbitrary code when running 'go build'. The line directive requires the absolute path of the file in which the directive lives, which makes exploiting this issue significantly more complex. (CVE-2023-39323)

 - The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. (CVE-2023-44487)

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 golang packages.
