Description
This security bulletin contains information about 7 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) Input validation error (CVE-ID: CVE-2021-20329)
The vulnerability allows a remote attacker to manipulate data
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can inject additional fields into marshalled documents and manipulate data in the database.
4) Resource management error (CVE-ID: CVE-2022-41724)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources in crypto/tls when handling large TLS handshake records. A remote attacker can send specially crafted data to the application and perform a denial of service (DoS) attack.
The vulnerability affects all TLS 1.3 clients, TLS 1.2 clients which explicitly enable session resumption (by setting Config.ClientSessionCache to a non-nil value), and TLS 1.3 servers which request client certificates (by setting Config.ClientAuth >= RequestClientCert).
5) Resource exhaustion (CVE-ID: CVE-2022-41725)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper control over internal resources in net/http and mime/multipart. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
6) Resource exhaustion (CVE-ID: CVE-2023-25153)
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 importing an OCI image. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
7) Improper Privilege Management (CVE-ID: CVE-2023-25173)
The vulnerability allows a local user to escalate privileges.
The vulnerability exists due to improper privilege management where supplementary groups are not set up properly inside a container. A local user can use supplementary group access to bypass primary group restrictions and compromise the container.
