USN-5892-1: NSS vulnerabilities It was discovered that NSS incorrectly handled client authentication without a user certificate in the database. A remote attacker could possibly use this issue to cause a NSS client to crash, resulting in a denial of service. This issue only affected Ubuntu 22.10. (CVE-2022-3479) Christian Holler discovered that NSS incorrectly handled certain PKCS 12 certificated bundles. A remote attacker could use this issue to cause NSS to crash, leading to a denial of service, or possibly execute arbitrary code. (CVE-2023-0767) Source: USN-5892-1: NSS vulnerabilities

USN-5891-1: curl vulnerabilities Harry Sintonen discovered that curl incorrectly handled HSTS support when multiple URLs are requested serially. A remote attacker could possibly use this issue to cause curl to use unencrypted connections. This issue only affected Ubuntu 22.04 LTS, and Ubuntu 22.10. (CVE-2023-23914) Harry Sintonen discovered that curl incorrectly handled HSTS support when multiple URLs are requested in parallel. A remote attacker could possibly use this issue to cause curl to use unencrypted connections. This issue only affected Ubuntu 22.04 LTS, and Ubuntu 22.10. (CVE-2023-23915) Patrick Monnerat discovered that curl incorrectly handled memory when processing requests with multi-header compression. A remote attacker could possibly use this issue to cause curl to consume resources, leading to a denial of service. (CVE-2023-23916) Source: USN-5891-1: curl vulnerabilities

USN-5890-1: Open vSwitch vulnerabilities Qian Chen discovered that Open vSwitch incorrectly handled certain Organization Specific TLVs. A remote attacker could use this issue to cause Open vSwitch to crash, resulting in a denial of service, or possibly execute arbitrary code. Source: USN-5890-1: Open vSwitch vulnerabilities

USN-5889-1: ZoneMinder vulnerabilities It was discovered that ZoneMinder was not properly sanitizing URL parameters for certain views. An attacker could possibly use this issue to perform a cross-site scripting (XSS) attack. This issue was only fixed in Ubuntu 16.04 ESM. (CVE-2019-6777) It was discovered that ZoneMinder was not properly sanitizing stored user input later printed to the user in certain views. An attacker could possibly use this issue to perform a cross-site scripting (XSS) attack. This issue was only fixed in Ubuntu 16.04 ESM. (CVE-2019-6990, CVE-2019-6992) It was discovered that ZoneMinder was not properly limiting data size and not properly performing bound checks when processing username and password data, which could lead to a stack buffer overflow. An attacker could possibly use this issue to bypass authentication, cause a denial of service or execute arbitrary code. This issue was only [ more… ]
