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" } } ] } }
