{"id":"AZL-97407","summary":"CVE-2026-58050 affecting package rust for versions less than 1.75.0-30","details":"libssh2 through 1.11.1 reads an attacker-controlled 32-bit attribute count from a publickey-subsystem response and uses it in the allocation num_attrs * sizeof(libssh2_publickey_attribute) without bounds checking, so on 32-bit platforms the multiplication overflows to an undersized buffer. A malicious SSH server can then drive the attribute-parsing loop to write past the allocation, causing a heap buffer overflow in a connecting libssh2 client.","modified":"2026-09-09T14:18:11.826033021Z","published":"2026-06-28T02:16:32Z","upstream":["CVE-2026-58050"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58050"}],"affected":[{"package":{"name":"rust","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/rust"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.75.0-30"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-97407.json"}}],"schema_version":"1.9.0"}
