USN-6117-1: Apache Batik vulnerabilities It was discovered that Apache Batik incorrectly handled certain inputs. An attacker could possibly use this to perform a cross site request forgery attack. (CVE-2019-17566, CVE-2020-11987, CVE-2022-38398, CVE-2022-38648) It was discovered that Apache Batik incorrectly handled Jar URLs in some situations. A remote attacker could use this issue to access files on the server. (CVE-2022-40146) It was discovered that Apache Batik allowed running untrusted Java code from an SVG. An attacker could use this issue to cause a denial of service, or possibly execute arbitrary code. (CVE-2022-41704, CVE-2022-42890) Source: USN-6117-1: Apache Batik vulnerabilities

USN-6119-1: OpenSSL vulnerabilities Matt Caswell discovered that OpenSSL incorrectly handled certain ASN.1 object identifiers. A remote attacker could possibly use this issue to cause OpenSSL to consume resources, resulting in a denial of service. (CVE-2023-2650) Anton Romanov discovered that OpenSSL incorrectly handled AES-XTS cipher decryption on 64-bit ARM platforms. An attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. This issue only affected Ubuntu 22.04 LTS, Ubuntu 22.10, and Ubuntu 23.04.

USN-6118-1: Linux kernel (Oracle) vulnerabilities Zheng Wang discovered that the Intel i915 graphics driver in the Linux kernel did not properly handle certain error conditions, leading to a double-free. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-3707) Jordy Zomer and Alexandra Sandulescu discovered that the Linux kernel did not properly implement speculative execution barriers in usercopy functions in certain situations. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2023-0459) It was discovered that the TLS subsystem in the Linux kernel contained a type confusion vulnerability in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2023-1075) It was discovered that the Reliable Datagram Sockets (RDS) protocol implementation in the Linux kernel contained a type confusion vulnerability [ more… ]

USN-6115-1: TeX Live vulnerability Max Chernoff discovered that LuaTeX (TeX Live) did not properly disable shell escape. An attacker could possibly use this issue to execute arbitrary shell commands. Source: USN-6115-1: TeX Live vulnerability

USN-6116-1: hawk vulnerability It was discovered that hawk incorrectly handled certain inputs. If a user or an automated system were tricked into opening a specially crafted input file, a remote attacker could possibly use this issue to cause a denial of service.
