USN-5710-1: OpenSSL vulnerabilities It was discovered that OpenSSL incorrectly handled certain X.509 Email Addresses. If a certificate authority were tricked into signing a specially-crafted certificate, a remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. The default compiler options for affected releases reduce the vulnerability to a denial of service. (CVE-2022-3602, CVE-2022-3786) It was discovered that OpenSSL incorrectly handled applications creating custom ciphers via the legacy EVP_CIPHER_meth_new() function. This issue could cause certain applications that mishandled values to the function to possibly end up with a NULL cipher and messages in plaintext.

USN-5709-1: Firefox vulnerabilities Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information across domains, or execute arbitrary code. (CVE-2022-42927, CVE-2022-42928, CVE-2022-42929, CVE-2022-42930, CVE-2022-42932) It was discovered that Firefox saved usernames to a plaintext file. A local user could potentially exploit this to obtain sensitive information. (CVE-2022-42931) Source: USN-5709-1: Firefox vulnerabilities

USN-5708-1: backport-iwlwifi-dkms vulnerabilities Sönke Huster discovered that an integer overflow vulnerability existed in the WiFi driver stack in the Linux kernel, leading to a buffer overflow. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-41674) Sönke Huster discovered that a use-after-free vulnerability existed in the WiFi driver stack in the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-42719) Sönke Huster discovered that the WiFi driver stack in the Linux kernel did not properly perform reference counting in some situations, leading to a use-after-free vulnerability. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-42720) Sönke Huster discovered that the WiFi driver stack [ more… ]
