{"id":"AZL-11515","summary":"CVE-2022-45939 affecting package emacs for versions less than 28.1-5","details":"GNU Emacs through 28.2 allows attackers to execute commands via shell metacharacters in the name of a source-code file, because lib-src/etags.c uses the system C library function in its implementation of the ctags program. For example, a victim may use the \"ctags *\" command (suggested in the ctags documentation) in a situation where the current working directory has contents that depend on untrusted input.","modified":"2026-04-21T04:22:11.580752Z","published":"2022-11-28T06:15:10Z","upstream":["CVE-2022-45939"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-45939"}],"affected":[{"package":{"name":"emacs","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/emacs"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"28.1-5"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-11515.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
