Description

This security bulletin contains information about 9 secuirty vulnerabilities.

1) 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".

2) Incorrect Regular Expression (CVE-ID: CVE-2022-40899)

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

The vulnerability exists due to improper input validation when processing the Set-Cookie header. A remote attacker can send a specially crafted HTTP request to the application and perform a regular expression denial of service (ReDoS) attack.

3) 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.

4) 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.

5) Code Injection (CVE-ID: CVE-2023-29404)

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

The vulnerability exists within Go runtime when running "go get" on a malicious module, or when running any other
command which builds untrusted code.A remote attacker can inject and execute arbitrary code on the target system at build time when using cgo.

6) Code Injection (CVE-ID: CVE-2023-29405)

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

The vulnerability exists within Go runtime when running "go get" on a malicious module, or when running any other
command which builds untrusted code.A remote attacker can inject and execute arbitrary code on the target system at build time when using cgo.

7) Code Injection (CVE-ID: CVE-2023-29402)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to improper input validation within the cgo go command when building code that contains directories with newline characters in their names. A remote attacker can pass specially crafted input to the cgo command at build time and potentially compromise the system.

Modules which are retrieved using the go command, i.e. via "go get", are not affected (modules retrieved using GOPATH-mode, i.e. GO111MODULE=off, may be affected).

8) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-29403)

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

The vulnerability exists within Go runtime due to application allows to execute setuid/setgid binaries without any restrictions. An attacker with ability to control the application flow can execute arbitrary code on the system with elevated privileges.

9) Insufficient verification of data authenticity (CVE-ID: CVE-2023-37920)

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exist due to software recognizes "e-Tugra" root certificates, which were subject to an investigation prompted by reporting of security issues in their systems. An attacker with ability to generate certificates signed with the  compromised "e-Tugra" root certificate can perform MitM attack.
