Description

This security bulletin contains information about 6 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) 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.


4) 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.


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.
