An attacker may use the GRUB 2 flaw to hijack and tamper the GRUB verification process. This flaw also allows the bypass of Secure Boot protections. In order to load an untrusted or modified kernel, an attacker would first need to establish access to the system such as gaining physical access, obtain the ability to alter a pxe-boot network, or have remote access to a networked system with root access. With this access, an attacker could then craft a string to cause a buffer overflow by injecting a malicious payload that leads to arbitrary code execution within GRUB. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.","title":"CVE description"}],"product_status":{"recommended":["SUSE Linux Enterprise Module for Basesystem 15 SP1:shim-15+git47-3.8.1.x86_64","SUSE Linux Enterprise Module for Basesystem 15 SP2:shim-15+git47-3.8.1.x86_64"]},"references":[{"category":"external","summary":"CVE-2020-10713","url":"https://www.suse.com/security/cve/CVE-2020-10713"},{"category":"external","summary":"SUSE Bug 1168994 for CVE-2020-10713","url":"https://bugzilla.suse.com/1168994"},{"category":"external","summary":"SUSE Bug 1173456 for CVE-2020-10713","url":"https://bugzilla.suse.com/1173456"},{"category":"external","summary":"SUSE Bug 1173812 for CVE-2020-10713","url":"https://bugzilla.suse.com/1173812"},{"category":"external","summary":"SUSE Bug 1199353 for CVE-2020-10713","url":"https://bugzilla.suse.com/1199353"}],"remediations":[{"category":"vendor_fix","details":"To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or \"zypper patch\".\n","product_ids":["SUSE Linux Enterprise Module for Basesystem 15 SP1:shim-15+git47-3.8.1.x86_64","SUSE Linux Enterprise Module for Basesystem 15 SP2:shim-15+git47-3.8.1.x86_64"]}],"scores":[{"cvss_v3":{"baseScore":8.2,"baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"products":["SUSE Linux Enterprise Module for Basesystem 15 SP1:shim-15+git47-3.8.1.x86_64","SUSE Linux Enterprise Module for Basesystem 15 SP2:shim-15+git47-3.8.1.x86_64"]}],"threats":[{"category":"impact","date":"2020-09-14T16:12:03Z","details":"important"}],"title":"CVE-2020-10713"}]}
