USN-6264-1: WebKitGTK vulnerabilities Several security issues were discovered in the WebKitGTK Web and JavaScript engines. If a user were tricked into viewing a malicious website, a remote attacker could exploit a variety of issues related to web browser security, including cross-site scripting attacks, denial of service attacks, and arbitrary code execution.

USN-6262-1: Wireshark vulnerabilities It was discovered that Wireshark did not properly handle certain NFS packages when certain configuration options were enabled. An attacker could possibly use this issue to cause Wireshark to crash, resulting in a denial of service. (CVE-2020-13164) It was discovered that Wireshark did not properly handle certain GVCP packages. An attacker could possibly use this issue to cause Wireshark to crash, resulting in a denial of service. This issue only affected Ubuntu 20.04 LTS. (CVE-2020-15466) It was discovered that Wireshark did not properly handle certain Kafka packages. An attacker could possibly use this issue to cause Wireshark to crash, resulting in a denial of service. This issue only affected Ubuntu 20.04 LTS. (CVE-2020-17498) It was discovered that Wireshark did not properly handle certain TCP packages containing an invalid 0xFFFF checksum. An attacker could possibly use this issue [ more… ]

USN-6261-1: Linux kernel (IoT) vulnerabilities It was discovered that the IP-VLAN network driver for the Linux kernel did not properly initialize memory in some situations, leading to 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-2023-3090) Shir Tamari and Sagi Tzadik discovered that the OverlayFS implementation in the Ubuntu Linux kernel did not properly perform permission checks in certain situations. A local attacker could possibly use this to gain elevated privileges. (CVE-2023-32629) It was discovered that the netfilter subsystem in the Linux kernel did not properly handle some error conditions, 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-2023-3390) Tanguy Dubroca discovered that the netfilter subsystem in the Linux [ more… ]

USN-6260-1: Linux kernel vulnerabilities It was discovered that the NTFS file system implementation in the Linux kernel did not properly check buffer indexes in certain situations, leading to an out-of-bounds read vulnerability. A local attacker could possibly use this to expose sensitive information (kernel memory). (CVE-2022-48502) Stonejiajia, Shir Tamari and Sagi Tzadik discovered that the OverlayFS implementation in the Ubuntu Linux kernel did not properly perform permission checks in certain situations. A local attacker could possibly use this to gain elevated privileges. (CVE-2023-2640) It was discovered that the IP-VLAN network driver for the Linux kernel did not properly initialize memory in some situations, leading to 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-2023-3090) Mingi Cho discovered that the netfilter subsystem in the Linux kernel [ more… ]

USN-6259-1: Open-iSCSI vulnerabilities Jos Wetzels, Stanislav Dashevskyi, and Amine Amri discovered that Open-iSCSI incorrectly handled certain checksums for IP packets. An attacker could possibly use this issue to expose sensitive information. (CVE-2020-13987) Jos Wetzels, Stanislav Dashevskyi, Amine Amri discovered that Open-iSCSI incorrectly handled certain parsing TCP MSS options. An attacker could possibly use this issue to cause a crash or cause unexpected behavior. (CVE-2020-13988) Amine Amri and Stanislav Dashevskyi discovered that Open-iSCSI incorrectly handled certain TCP data. An attacker could possibly use this issue to expose sensitive information.
