Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2023-44487)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improperly control of consumption for internal resources when handling HTTP/2 requests with compressed HEADERS frames. A remote attacker can send a sequence of compressed HEADERS frames followed by RST_STREAM frames and perform a denial of service (DoS) attack, a.k.a. "Rapid Reset".
Note, the vulnerability is being actively exploited in the wild.
2) 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.
3) Resource exhaustion (CVE-ID: CVE-2023-39326)
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 when handling HTTP chunked requests. A remote attacker can send specially crafted HTTP requests to the server and consume excessive memory resources.
4) Observable discrepancy (CVE-ID: CVE-2023-45287)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to a timing discrepancy when handling RSA based TLS key exchanges. A remote attacker can perform a Marvin attack and gain access to sensitive information.
5) 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.
6) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2023-40225)
The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.
The vulnerability exists due to improper validation of HTTP requests. A remote attacker can send a specially crafted HTTP request with empty Content-Length headers to the server and smuggle arbitrary HTTP headers.
Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.
7) Resource exhaustion (CVE-ID: CVE-2023-47108)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to grpc Unary Server Interceptor does not properly control consumption of internal resources when processing multiple requests. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
8) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-6476)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to unchecked access to an experimental annotation. A remote user can use the cgroupv2 and perform a denial of service (DoS) attack by consuming all available memory resources.
9) Security features bypass (CVE-ID: CVE-2024-21626)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to an internal file descriptor leak that can cause a newly-spawned container process (from runc exec) to have a working directory in the host filesystem namespace or a malicious image to allow a container process to gain access to the host filesystem through runc run. A remote attacker can trick the victim into loading a malicious image to bypass sandbox restrictions and execute arbitrary code on the host OS.
