{"id":"DEBIAN-CVE-2025-0838","details":"There exists a heap buffer overflow vulnerable in Abseil-cpp. The sized constructors, reserve(), and rehash() methods of absl::{flat,node}hash{set,map} did not impose an upper bound on their size argument. As a result, it was possible for a caller to pass a very large size that would cause an integer overflow when computing the size of the container's backing store, and a subsequent out-of-bounds memory write. Subsequent accesses to the container might also access out-of-bounds memory. We recommend upgrading past commit 5a0e2cb5e3958dd90bb8569a2766622cb74d90c1","modified":"2026-09-01T16:06:08.356804075Z","published":"2025-02-21T15:15:11.890Z","upstream":["CVE-2025-0838"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2025-0838"}],"affected":[{"package":{"name":"abseil","ecosystem":"Debian:12","purl":"pkg:deb/debian/abseil?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"20220623.1-1+deb12u1"}]}],"versions":["20220623.1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2025-0838.json"}},{"package":{"name":"abseil","ecosystem":"Debian:13","purl":"pkg:deb/debian/abseil?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"20240722.0-3"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2025-0838.json"}},{"package":{"name":"abseil","ecosystem":"Debian:14","purl":"pkg:deb/debian/abseil?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"20240722.0-3"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2025-0838.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
