Description

This security bulletin contains information about 4 vulnerabilities.


1) Resource exhaustion (CVE-ID: CVE-2023-44487)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:A/U:Amber


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.


2) Resource exhaustion (CVE-ID: CVE-2024-25026)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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

The vulnerability exists due to application does not properly control consumption of internal resources when handling HTTP requests. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


3) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2023-50312)

CWE-ID: CWE-327 - Use of a Broken or Risky Cryptographic Algorithm

CVSSv4: CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows an adjacent attacker to gain access to potentially sensitive information.

The vulnerability exists due to weaker than expected security for outbound TLS connections caused by a failure to honor user configuration. An adjacent attacker can gain unauthorized access to sensitive information on the system.


4) Resource management error (CVE-ID: CVE-2023-46158)

CWE-ID: CWE-399 - Resource Management Errors

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


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

The vulnerability exists due to improper resource expiration handling. A remote attacker can bypass implemented security restrictions.
