USN-6196-1: ReportLab vulnerability It was discovered that ReportLab incorrectly handled certain PDF files. An attacker could possibly use this issue to execute arbitrary code. Source: USN-6196-1: ReportLab vulnerability

USN-6195-1: Vim vulnerabilities It was discovered that Vim contained an out-of-bounds read vulnerability. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code. (CVE-2022-0128) It was discovered that Vim did not properly manage memory when freeing allocated memory. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code. (CVE-2022-0156) It was discovered that Vim contained a heap-based buffer overflow vulnerability. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code. (CVE-2022-0158) It was discovered that Vim did not properly manage memory when recording and using select mode. An attacker could possibly use this issue to cause a denial of service. (CVE-2022-0393) It was discovered that Vim incorrectly handled certain memory operations during a visual block yank. An attacker could [ more… ]

USN-6194-1: Linux kernel (OEM) vulnerabilities Hangyu Hua discovered that the Flower classifier implementation in the Linux kernel contained an out-of-bounds write vulnerability. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-35788, LP: #2023577) Xingyuan Mo and Gengjia Chen discovered that the io_uring subsystem in the Linux kernel did not properly handle locking when IOPOLL mode is being used. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-2430) Wei Chen discovered that the InfiniBand RDMA communication manager implementation in the Linux kernel contained an out-of-bounds read vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-2176) It was discovered that for some Intel processors the INVLPG instruction implementation did not properly flush global TLB entries when PCIDs are enabled. [ more… ]

USN-6193-1: Linux kernel vulnerabilities Hangyu Hua discovered that the Flower classifier implementation in the Linux kernel contained an out-of-bounds write vulnerability. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-35788, LP: #2023577) It was discovered that for some Intel processors the INVLPG instruction implementation did not properly flush global TLB entries when PCIDs are enabled. An attacker could use this to expose sensitive information (kernel memory) or possibly cause undesired behaviors. (LP: #2023220) Source: USN-6193-1: Linux kernel vulnerabilities

USN-6192-1: Linux kernel vulnerabilities Hangyu Hua discovered that the Flower classifier implementation in the Linux kernel contained an out-of-bounds write vulnerability.
