A zero-count ASCII entry sets `entry->size` to 0, and the derived length reaches i_tags_add() as -1, which is interpreted as a request to call strlen(), scanning past the entry to the next NUL and copying those bytes into the tag. JPEG reaches this path via im_decode_exif(), as does the separate Imager::File::WEBP distribution, which is fixed by upgrading Imager.\n\nAny caller of Imager->read() on an attacker-supplied image with such an entry may receive an exif_* tag holding adjacent heap bytes instead of an empty string."}],"problemTypes":[{"descriptions":[{"cweId":"CWE-125","description":"CWE-125 Out-of-bounds Read","lang":"en","type":"CWE"}]}],"providerMetadata":{"orgId":"9b29abf9-4ab0-4765-b253-1875cd9b441e","shortName":"CPANSec","dateUpdated":"2026-08-07T17:56:49.592Z"},"references":[{"tags":["vendor-advisory"],"url":"https://github.com/tonycoz/imager/security/advisories/GHSA-hx46-55wp-hv6m"},{"tags":["patch"],"url":"https://github.com/tonycoz/imager/commit/24bde0427a113264d53f45a9c29ae756d84c82fe.patch"},{"tags":["release-notes"],"url":"https://metacpan.org/release/TONYC/Imager-1.034/changes"}],"solutions":[{"lang":"en","value":"Upgrade to Imager 1.034 or later."}],"source":{"discovery":"UNKNOWN"},"timeline":[{"lang":"en","time":"2026-08-07T00:00:00.000Z","value":"Version 1.034 released with fix."}],"title":"Imager versions from 0.45_02 before 1.034 for Perl may expose adjacent heap bytes via strlen() over-read from zero-count ASCII EXIF entries in copy_string_tags","x_generator":{"engine":"cpansec-cna-tool 0.1"}},"adp":[{"references":[{"url":"https://github.com/tonycoz/imager/security/advisories/GHSA-hx46-55wp-hv6m","tags":["exploit"]}],"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":7.5,"attackVector":"NETWORK","baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","integrityImpact":"NONE","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"NONE","privilegesRequired":"NONE","confidentialityImpact":"HIGH"}},{"other":{"type":"ssvc","content":{"timestamp":"2026-08-07T18:21:43.252440Z","id":"CVE-2026-19082","options":[{"Exploitation":"poc"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-08-07T18:23:05.483Z"}},{"title":"CVE Program Container","references":[{"url":"http://www.openwall.com/lists/oss-security/2026/08/07/6"}],"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2026-08-07T20:13:18.224Z"}}]}}
