SB20231018153 - Anolis OS update for golang

Description

This security bulletin contains information about 6 secuirty vulnerabilities.

1) Improper Neutralization of HTTP Headers for Scripting Syntax (CVE-ID: CVE-2023-29406)

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to improper input validation in HTTP/1 client when handling HTTP Host header. A remote non-authenticated attacker can send a specially crafted HTTP request with a maliciously crafted Host header and inject additional headers or entire requests.

Successful exploitation of the vulnerability may allow an attacker to perform cross-site scripting, cache poisoning or session hijacking attacks.

2) Improper Certificate Validation (CVE-ID: CVE-2023-29409)

The vulnerability allows a remote attacker to compromise the target system.

The vulnerability exists due to verifying certificate chains containing large RSA keys is slow. A remote attacker can cause a client/server to expend significant CPU time verifying signatures.

3) Cross-site scripting (CVE-ID: CVE-2023-39319)

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists within the html/template package caused by improperly applied rules for handling occurrences of "<script", "<!--", and "</script" within JS literals in <script> contexts. A remote attacker can pass specially crafted input to the application and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

4) Input validation error (CVE-ID: CVE-2023-39321)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input in crypto/tls when processing  post-handshake message on QUIC connections. A remote attacker can send an incomplete post-handshake message for a QUIC connection and perform a denial of service (DoS) attack.

5) Input validation error (CVE-ID: CVE-2023-39322)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input in crypto/tls when processing  post-handshake message on QUIC connections. A remote attacker can send an incomplete post-handshake message for a QUIC connection and perform a denial of service (DoS) attack.

6) Input validation error (CVE-ID: CVE-2023-39323)

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to insufficient validation of user-supplied input when processing line directives (e.g. "//line") in the code. A remote attacker can bypass 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".

Remediation
