Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) 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.
2) 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.
3) 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.
4) Cross-site scripting (CVE-ID: CVE-2023-39319)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists within the html/template package caused by improperly applied rules for handling occurrences of "<script", "<!--", and "</script" within JS literals in <script> contexts. A remote attacker can pass specially crafted input to the application and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
5) 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.
6) 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.
