{"id":"USN-6937-1","summary":"openssl vulnerabilities","details":"It was discovered that OpenSSL incorrectly handled TLSv1.3 sessions when\ncertain non-default TLS server configurations were in use. A remote\nattacker could possibly use this issue to cause OpenSSL to consume\nresources, leading to a denial of service. (CVE-2024-2511)\n\nIt was discovered that OpenSSL incorrectly handled checking excessively\nlong DSA keys or parameters. A remote attacker could possibly use this\nissue to cause OpenSSL to consume resources, leading to a denial of\nservice. This issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS.\n(CVE-2024-4603)\n\nWilliam Ahern discovered that OpenSSL incorrectly handled certain memory\noperations in a rarely-used API. A remote attacker could use this issue to\ncause OpenSSL to crash, resulting in a denial of service, or possibly\nexecute arbitrary code. (CVE-2024-4741)\n\nJoseph Birr-Pixton discovered that OpenSSL incorrectly handled calling a\ncertain API with an empty supported client protocols buffer. A remote\nattacker could possibly use this issue to obtain sensitive information, or\ncause OpenSSL to crash, resulting in a denial of service.
