Description

This security bulletin contains information about 7 secuirty vulnerabilities.


1) Security features bypass (CVE-ID: CVE-2022-31629)

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to the way PHP handles HTTP variable names. A remote attacker can set a standard insecure cookie in the victim's browser which is treated as a `__Host-` or `__Secure-` cookie by PHP applications.


2) Security Features (CVE-ID: CVE-2020-17049)

The vulnerability allows a remote user to bypass authentication process.

The vulnerability exists due to security feature bypass issue in Kerberos. A remote administrator can bypass authentication process and gain unauthorized access to the application.


3) Out-of-bounds read (CVE-ID: CVE-2024-37371)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition when handling GSS message token. A remote attacker can send specially crafted token to the application, trigger an out-of-bounds read error and read contents of memory on the system.


4) Input validation error (CVE-ID: CVE-2024-28182)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to reading the unbounded number of HTTP/2 CONTINUATION frames. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.


5) Missing Release of Resource after Effective Lifetime (CVE-ID: CVE-2024-2398)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to an error when sending HTTP/2 server push responses with an overly large number of headers. A remote attacker can send PUSH_PROMISE frames with an excessive amount of headers to the application, trigger memory leak and perform a denial of service (DoS) attack.


6) Security features bypass (CVE-ID: CVE-2024-2756)

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to the way PHP handles HTTP variable names. A remote attacker can set a standard insecure cookie in the victim's browser which is treated as a `__Host-` or `__Secure-` cookie by PHP applications.

Note, the vulnerability exists due to incomplete fix for #VU67756 (CVE-2022-31629).


7) Information Exposure Through Timing Discrepancy (CVE-ID: CVE-2024-2236)

The vulnerability allows a remote attacker to perform timing attack.

The vulnerability exists due to an error in libgcrypt's RSA implementation. A remote attacker can initiate a Bleichenbacher-style attack, which can lead to the decryption of RSA ciphertexts.
