Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2023-43642)

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

The vulnerability exists due to missing upper bound check on chunk length. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


2) Resource exhaustion (CVE-ID: CVE-2022-45061)

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

The vulnerability exists due to usage of an unnecessary quadratic algorithm in one path when processing some inputs to the IDNA (RFC 3490) decoder. A remote attacker can pass a specially crafted name to he decoder, trigger resource excessive CPU consumption and perform a denial of service (DoS) attack.


3) Cleartext transmission of sensitive information (CVE-ID: CVE-2023-40217)

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to an error in ssl.SSLSocket implementation when handling TLS client authentication. A remote attacker can trick the application to send data unencrypted.


4) SQL injection (CVE-ID: CVE-2023-39417)

The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.

The vulnerability exists due to insufficient sanitization of user-supplied data within the extension script @substitutions@, which uses @extowner@, @extschema@, or @extschema:...@ inside a quoting construct. A remote attacker can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database.


5) 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".


6) Resource exhaustion (CVE-ID: CVE-2023-39325)

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

The vulnerability exists due to excessive consumption of internal resources when handling HTTP/2 requests. A remote attacker can bypass the http2.Server.MaxConcurrentStreams setting by creating new connections while the current connections are still being processed, trigger resource exhaustion and perform a denial of service (DoS) attack.
