------------------------------------------------------------------------- Debian LTS Advisory DLA-4800-1 debian-lts@lists.debian.org https://www.debian.org/lts/security/ Carlos Henrique Lima Melara September 29, 2026 https://wiki.debian.org/LTS ------------------------------------------------------------------------- Package : glance Version : 2:25.1.0-2+deb12u5 CVE ID : CVE-2026-71196 CVE-2026-71197 CVE-2026-71198 CVE-2026-77648 Debian Bug : 1144212 1146594 Multiple vulnerabilities were discovered in Glance, OpenStack's image storage service. CVE-2026-71196, CVE-2026-71197 and CVE-2026-71198 / OSSA-2026-038 Three related Server-Side Request Forgery (SSRF) vulnerabilities in the web-download import method and HTTP image location APIs: insecure default URI filtering permitted an authenticated user to fetch arbitrary internal URLs, including cloud metadata endpoints; the URI validator did not perform DNS resolution before applying host filters, allowing bypass via attacker-controlled domains and DNS rebinding attacks; and when the HTTP store was enabled, the image location API lacked host filtering entirely, storing fetched content as downloadable image data, converting blind SSRF into full-read exfiltration. An unbounded fetch when the source omitted Content-Length could also fill the disk (image_size_cap is now honored). CVE-2026-77648 / OSSN-0105 The legacy (deprecated) /v2/tasks API accepted type=import tasks which bypassed the import URI filtering (host, port and path restrictions) enforced by the modern image import, allowing an admin to fetch internal URLs from the Glance service network (SSRF). Legacy import URIs are now validated the same way as modern import. For Debian 12 bookworm, these problems have been fixed in version 2:25.1.0-2+deb12u5. We recommend that you upgrade your glance packages.
