{"id":"PYSEC-2023-233","details":"Exiv2 is a C++ library and a command-line utility to read, write, delete and modify Exif, IPTC, XMP and ICC image metadata. An out-of-bounds write was found in Exiv2 version v0.28.0. The vulnerable function, `BmffImage::brotliUncompress`, is new in v0.28.0, so earlier versions of Exiv2 are _not_ affected. The out-of-bounds write is triggered when Exiv2 is used to read the metadata of a crafted image file. An attacker could potentially exploit the vulnerability to gain code execution, if they can trick the victim into running Exiv2 on a crafted image file. This bug is fixed in version v0.28.1. Users are advised to upgrade. There are no known workarounds for this vulnerability.","aliases":["CVE-2023-44398","GHSA-hrw9-ggg3-3r4r"],"modified":"2025-10-09T08:26:40.736495Z","published":"2023-11-06T18:15:00Z","references":[{"type":"ADVISORY","url":"https://github.com/Exiv2/exiv2/security/advisories/GHSA-hrw9-ggg3-3r4r"},{"type":"FIX","url":"https://github.com/Exiv2/exiv2/commit/e884a0955359107f4031c74a07406df7e99929a5"}],"affected":[{"package":{"name":"exiv2","ecosystem":"PyPI","purl":"pkg:pypi/exiv2"},"ranges":[{"type":"GIT","repo":"https://github.com/Exiv2/exiv2","events":[{"introduced":"0"},{"fixed":"e884a0955359107f4031c74a07406df7e99929a5"}]},{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.1","0.11.0","0.11.1","0.11.2","0.11.3","0.12.0","0.12.1","0.13.0","0.13.1","0.13.2","0.14.0","0.14.1","0.2","0.3","0.3.1","0.15.0","0.16.0","0.16.1","0.16.2","0.16.2.post1","0.16.3","0.16.3.post1","0.17.0","0.17.1","0.17.2","0.17.3","0.17.4","0.17.5"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/exiv2/PYSEC-2023-233.yaml"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
