CVEID:CVE-2023-6129
**DESCRIPTION:**OpenSSL is vulnerable to a denial of service, caused by a flaw in the POLY1305 MAC (message authentication code) implementation. By sending a specially crafted request, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 5.9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/278934 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2024-0727
**DESCRIPTION:**OpenSSL is vulnerable to a denial of service, caused by improper input validation. By persuading a victim to open a specially crafted PKCS12 file, a remote attacker could exploit this vulnerability to cause the application to crash.
CVSS Base score: 3.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/280532 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:L)

CVEID:CVE-2024-22201
**DESCRIPTION:**Eclipse Jetty is vulnerable to a denial of service, caused by a flaw when an HTTP/2 connection gets TCP congested. By sending a specially crafted request, a remote attacker could exploit this vulnerability to cause the server to stop accepting new connections from valid clients, and results in a denial of service condition.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/284253 for the current score.
