USN-5975-1: Linux kernel vulnerabilities It was discovered that the Upper Level Protocol (ULP) subsystem in the Linux kernel did not properly handle sockets entering the LISTEN state in certain protocols, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-0461) It was discovered that the System V IPC implementation in the Linux kernel did not properly handle large shared memory counts. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2021-3669) It was discovered that an out-of-bounds write vulnerability existed in the Video for Linux 2 (V4L2) implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-20369) Pawan Kumar Gupta, Alyssa Milburn, Amit Peled, Shani [ more… ]

USN-5974-1: GraphicsMagick vulnerabilities It was discovered that GraphicsMagick was not properly performing bounds checks when processing TGA image files, which could lead to a heap buffer overflow. If a user or automated system were tricked into processing a specially crafted TGA image file, an attacker could possibly use this issue to cause a denial of service or execute arbitrary code. This issue only affected Ubuntu 14.04 ESM and Ubuntu 16.04 ESM. (CVE-2018-20184) It was discovered that GraphicsMagick was not properly validating bits per pixel data when processing DIB image files. If a user or automated system were tricked into processing a specially crafted DIB image file, an attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 14.04 ESM and Ubuntu 16.04 ESM. (CVE-2018-20189) It was discovered that GraphicsMagick was not properly processing [ more… ]

USN-5973-1: url-parse vulnerabilities It was discovered that url-parse 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, or to perform a server-side request forgery attack or open redirect attack. (CVE-2018-3774) It was discovered that url-parse 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 bypass input validation. This issue was only fixed in Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2020-8124) Yaniv Nizry discovered that url-parse 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 [ more… ]

USN-5964-2: curl vulnerabilities USN-5964-1 fixed several vulnerabilities in curl. This update provides the corresponding update for Ubuntu 14.04 ESM and Ubuntu 16.04 ESM. Original advisory details: Harry Sintonen discovered that curl incorrectly handled certain TELNET connection options. Due to lack of proper input scrubbing, curl could pass on user name and telnet options to the server as provided, contrary to expectations. (CVE-2023-27533) Harry Sintonen discovered that curl incorrectly reused certain FTP connections. This could lead to the wrong credentials being reused, contrary to expectations. (CVE-2023-27535) Harry Sintonen discovered that curl incorrectly reused connections when the GSS delegation option had been changed. This could lead to the option being reused, contrary to expectations. (CVE-2023-27536) Source: USN-5964-2: curl vulnerabilities
