{"id":"AZL-95855","summary":"CVE-2026-70453 affecting package rsync for versions less than 3.5.0-1","details":"rsync before 3.5.0 contains an algorithmic complexity vulnerability in the hash_search() function that allows a remote attacker to cause a denial of service by delivering a carefully constructed file list. A sender can exploit the quadratic-time worst-case behavior in hash lookups to exhaust receiver CPU resources with a modest number of crafted entries, causing a sustained denial of service.","modified":"2026-09-02T06:51:55Z","published":"2026-08-13T15:19:58Z","upstream":["CVE-2026-70453"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-70453"}],"affected":[{"package":{"name":"rsync","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/rsync"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.5.0-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-95855.json"}}],"schema_version":"1.9.0"}
