{"id":"AZL-41702","summary":"CVE-2017-7526 affecting package grub2 for versions less than 2.06-25","details":"libgcrypt before version 1.7.8 is vulnerable to a cache side-channel attack resulting into a complete break of RSA-1024 while using the left-to-right method for computing the sliding-window expansion. The same attack is believed to work on RSA-2048 with moderately more computation. This side-channel requires that attacker can run arbitrary software on the hardware where the private RSA key is used.","modified":"2026-04-01T05:14:24.014228Z","published":"2018-07-26T13:29:00Z","upstream":["CVE-2017-7526"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2017-7526"}],"affected":[{"package":{"name":"grub2","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/grub2"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.06-25"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-41702.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N"}]}
