Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Overly permissive cross-domain whitelist (CVE-ID: CVE-2022-1996)
The vulnerability allows a remote attacker to bypass the CORS protection mechanism.
The vulnerability exists due to incorrect processing of the "Origin" HTTP header that is supplied within HTTP request. A remote attacker can supply arbitrary value via the "Origin" HTTP header, bypass implemented CORS protection mechanism and perform cross-site scripting attacks against the vulnerable application.
2) Buffer overflow (CVE-ID: CVE-2022-24675)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists in the Golang's library encoding/pem. A remote attacker can send to victim a large (more than 5 MB) PEM input to cause a stack overflow in Decode and perform a denial of service (DoS) attack.
3) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2022-27191)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an error in golang.org/x/crypto/ssh before 0.0.0-20220314234659-1baeb1ce4c0b, as used in Go programming language. A remote attacker can crash a server in certain circumstances involving AddHostKey.
4) Integer overflow (CVE-ID: CVE-2022-28327)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to integer overflow in the Golang's library crypto/elliptic. A remote attacker can send a specially crafted scalar input longer than 32 bytes to cause P256().ScalarMult or P256().ScalarBaseMult to panic and perform a denial of service attack.
5) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2022-29526)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to the Faccessat function can incorrectly report that a file is accessible, when called with a non-zero flags parameter. An attacker can bypass implemented security restrictions.
6) Use of insufficiently random values (CVE-ID: CVE-2022-30629)
The vulnerability allows a remote attacker gain access to sensitive information.
The vulnerability exists in crypto/tls implementation when generating TLS tickets age. The newSessionTicketMsgTLS13.ageAdd is always set to "0" instead of a random value.
7) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2022-41717)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to excessive memory growth when handling HTTP/2 server requests. HTTP/2 server connections contain a cache of HTTP header keys sent by the client. While the total number of entries in this cache is capped, an attacker sending very large keys can cause the server to allocate approximately 64 MiB per open connection.
