It was discovered that OpenSSL incorrectly handled TLSv1.3 sessions when
certain non-default TLS server configurations were in use. A remote
attacker could possibly use this issue to cause OpenSSL to consume
resources, leading to a denial of service. (CVE-2024-2511)
It was discovered that OpenSSL incorrectly handled checking excessively
long DSA keys or parameters. A remote attacker could possibly use this
issue to cause OpenSSL to consume resources, leading to a denial of
service. This issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS.
(CVE-2024-4603)
William Ahern discovered that OpenSSL incorrectly handled certain memory
operations in a rarely-used API. A remote attacker could use this issue to
cause OpenSSL to crash, resulting in a denial of service, or possibly
execute arbitrary code. (CVE-2024-4741)
Joseph Birr-Pixton discovered that OpenSSL incorrectly handled calling a
certain API with an empty supported client protocols buffer. A remote
attacker could possibly use this issue to obtain sensitive information, or
cause OpenSSL to crash, resulting in a denial of service. (CVE-2024-5535)
