Description

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)
