{"id":"AZL-83024","summary":"CVE-2026-40339 affecting package libgphoto2 2.5.31-1","details":"libgphoto2 is a camera access and control library. Versions up to and including 2.5.33 have an out-of-bounds read in `ptp_unpack_Sony_DPD()` in `camlibs/ptp2/ptp-pack.c` (line 842). The function reads the FormFlag byte via `dtoh8o(data, *poffset)` without a prior bounds check. The standard `ptp_unpack_DPD()` at lines 686–687 correctly validates `*offset + sizeof(uint8_t) \u003e dpdlen` before this same read, but the Sony variant omits this check entirely. Commit 09f8a940b1e418b5693f5c11e3016a1ad2cea62d fixes the issue.","modified":"2026-08-29T05:25:22Z","published":"2026-04-18T00:16:37Z","upstream":["CVE-2026-40339"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-40339"}],"affected":[{"package":{"name":"libgphoto2","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/libgphoto2"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"2.5.31-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-83024.json"}}],"schema_version":"1.9.0"}
