{"id":"AZL-80904","summary":"CVE-2026-4647 affecting package gdb for versions less than 13.2-7","details":"A flaw was found in the GNU Binutils BFD library, a widely used component for handling binary files such as object files and executables. The issue occurs when processing specially crafted XCOFF object files, where a relocation type value is not properly validated before being used. This can cause the program to read memory outside of intended bounds. As a result, affected tools may crash or expose unintended memory contents, leading to denial-of-service or limited information disclosure risks.","modified":"2026-08-29T05:27:27Z","published":"2026-03-23T14:16:36Z","upstream":["CVE-2026-4647"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-4647"}],"affected":[{"package":{"name":"gdb","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/gdb"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"13.2-7"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-80904.json"}}],"schema_version":"1.9.0"}
