Description
This security bulletin contains information about 15 secuirty vulnerabilities.
1) Input validation error (CVE-ID: CVE-2022-21698)
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 within method label cardinality. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
2) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2022-27191)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an error in golang.org/x/crypto/ssh before 0.0.0-20220314234659-1baeb1ce4c0b, as used in Go programming language. A remote attacker can crash a server in certain circumstances involving AddHostKey.
3) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2022-41717)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to excessive memory growth when handling HTTP/2 server requests. HTTP/2 server connections contain a cache of HTTP header keys sent by the client. While the total number of entries in this cache is capped, an attacker sending very large keys can cause the server to allocate approximately 64 MiB per open connection.
4) Resource exhaustion (CVE-ID: CVE-2022-41723)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources in the HPACK decoder. A remote attacker can send a specially crafted HTTP/2 stream to the application, cause resource exhaustion and perform a denial of service (DoS) attack.
5) Cross-site scripting (CVE-ID: CVE-2023-3978)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
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.
7) Inadequate encryption strength (CVE-ID: CVE-2023-48795)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to incorrect implementation of the SSH Binary Packet Protocol (BPP), which mishandles the handshake phase and the use of sequence numbers. A remote attacker can perform MitM attack and delete the SSH2_MSG_EXT_INFO message sent before authentication starts, allowing the attacker to disable a subset of the keystroke timing obfuscation features introduced in OpenSSH 9.5.
The vulnerability was dubbed "Terrapin attack" and it affects both client and server implementations.
8) Input validation error (CVE-ID: CVE-2024-24789)
The vulnerability allows a remote attacker to manipulate data.
The vulnerability exists due to insufficient validation of user-supplied input in archive/zip when handling zip archives. A remote attacker can create a zip file with content that will vary depending on the implementation reading the file.
9) UNIX symbolic link following (CVE-ID: CVE-2024-52522)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a symlink following issue when copying to local disk. A local user can create a specially crafted symbolic link to a critical file on the system and overwrite it with privileges of the application.
Successful exploitation of this vulnerability may result in privilege escalation.
10) Improper authorization (CVE-ID: CVE-2024-45337)
The vulnerability allows a remote attacker to gain unauthorized access to the application.
The vulnerability exists due to improper authorization caused by improper usage of the ServerConfig.PublicKeyCallback callback. A remote attacker can bypass authorization in certain cases and gain access to the application.
11) Resource exhaustion (CVE-ID: CVE-2024-45338)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources in several Parse functions. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
12) Resource exhaustion (CVE-ID: CVE-2025-22868)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to the jws package does not properly control consumption of internal resources when handling malformed tokens. A remote attacker can pass a malformed JWT token to the application, trigger resource exhaustion and perform a denial of service (DoS) attack.
13) Resource exhaustion (CVE-ID: CVE-2025-22869)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources within the ssh package when handling clients that complete the key exchange slowly, or not at all. A remote user can trigger resource exhaustion and perform a denial of service (DoS) attack.
14) Input validation error (CVE-ID: CVE-2025-22870)
The vulnerability allows a remote attacker to alter application's behavior.
The vulnerability exists due to insufficient validation of an IPv6 zone ID as a hostname component, when matching hosts against proxy patterns. For instance the NO_PROXY environment variable is set to "*.example.com", a request to
"[::1%25.example.com]:80` will incorrectly match and not be proxied. A remote attacker can alter application behavior and potentially gain access to sensitive information or functionality.
15) Input validation error (CVE-ID: CVE-2025-22872)
The vulnerability allows a remote attacker to perform code injection attacks.
The vulnerability exists due to insufficient validation of tags with unquoted attribute values that end with a solidus character (/). The tokenizer can interpret such tags as self-closing, leading to content following such tags as being placed in the wrong scope during DOM construction.
