Description
This security bulletin contains information about 6 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) Path traversal (CVE-ID: CVE-2023-49569)
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences. A remote attacker can overwrite arbitrary files on the system. Applications are only affected if they are using the ChrootOS, which is the default when using "Plain" versions of Open and Clone funcs (e.g. PlainClone).
4) Resource exhaustion (CVE-ID: CVE-2023-49568)
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 responses from a Git server. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
5) Resource exhaustion (CVE-ID: CVE-2023-45142)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to incorrect processing of HTTP header User-Agent and HTTP method. A remote attacker can send multiple requests with long randomly generated HTTP methods or/and User agents and consume memory resources, leading to a denial of service condition.6) 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.
