{"id":"DEBIAN-CVE-2021-30022","details":"There is a integer overflow in media_tools/av_parsers.c in the gf_avc_read_pps_bs_internal in GPAC from 0.5.2 to 1.0.1. pps_id may be a negative number, so it will not return. However, avc-\u003epps only has 255 unit, so there is an overflow, which results a crash.","modified":"2026-08-27T23:04:42.075548987Z","published":"2021-04-19T20:15:14.647Z","upstream":["CVE-2021-30022"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2021-30022"}],"affected":[{"package":{"name":"gpac","ecosystem":"Debian:11","purl":"pkg:deb/debian/gpac?arch=source&distro=bullseye"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.0.1+dfsg1-4"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2021-30022.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
