{"id":"USN-6450-1","summary":"openssl vulnerabilities","details":"Tony Battersby discovered that OpenSSL incorrectly handled key and\ninitialization vector (IV) lengths. This could lead to truncation issues\nand result in loss of confidentiality for some symmetric cipher modes.\n(CVE-2023-5363)\n\nJuerg Wullschleger discovered that OpenSSL incorrectly handled the AES-SIV\ncipher. This could lead to empty data entries being ignored, resulting in\ncertain applications being misled. This issue only affected Ubuntu 22.04\nLTS and Ubuntu 23.04. (CVE-2023-2975)\n\nIt was discovered that OpenSSL incorrectly handled checking excessively\nlong DH keys or parameters. A remote attacker could possibly use this issue\nto cause OpenSSL to consume resources, leading to a denial of service. This\nissue only affected Ubuntu 22.04 LTS and Ubuntu 23.04.
