Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) 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).
2) 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.
3) Incorrect calculation (CVE-ID: CVE-2023-24532)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to the ScalarMult and ScalarBaseMult methods of the P256 Curve may return an incorrect result if called with some specific unreduced scalars.
4) Improper Neutralization of HTTP Headers for Scripting Syntax (CVE-ID: CVE-2023-29406)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to improper input validation in HTTP/1 client when handling HTTP Host header. A remote non-authenticated attacker can send a specially crafted HTTP request with a maliciously crafted Host header and inject additional headers or entire requests.
Successful exploitation of the vulnerability may allow an attacker to perform cross-site scripting, cache poisoning or session hijacking attacks.
5) Improper Certificate Validation (CVE-ID: CVE-2023-29409)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to verifying certificate chains containing large RSA keys is slow. A remote attacker can cause a client/server to expend significant CPU time verifying signatures.
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) 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.
8) Out-of-bounds read (CVE-ID: CVE-2023-4527)
The vulnerability allows a remote attacker to gain access to potentially sensitive information or perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the getaddrinfo() function called with the AF_UNSPEC address family. A remote attacker with control over DNS server can send a DNS response via TCP larger than 2048 bytes, trigger an out-of-bounds read and crash the application or gain access to potentially sensitive information.
Successful exploitation of the vulnerability requires that system is configured with no-aaaa mode via /etc/resolv.conf.
9) Use-after-free (CVE-ID: CVE-2023-4806)
The vulnerability allows an attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error within the getaddrinfo() function. A remote attacker can perform a denial of service (DoS) attack.
10) Use-after-free (CVE-ID: CVE-2023-4813)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error within the gaih_inet() function when the getaddrinfo() function is called and the hosts database in
/etc/nsswitch.conf is configured with SUCCESS=continue or SUCCESS=merge. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
11) Buffer overflow (CVE-ID: CVE-2023-4911)
The vulnerability allows a local user to escalate privileges on the system.
12) Buffer overflow (CVE-ID: CVE-2023-29491)
The vulnerability allows a local user to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing malformed data in a terminfo database file. A local user can trigger memory corruption and execute arbitrary code on the target system.
