{"apiVersion":"1.0","identifier":"CVE-2026-73434","description":"A flaw was found in GStreamer gst-plugins-good (avidemux). In gst_avi_demux_riff_parse_vprp(), the number of available gst_riff_vprp_video_field_desc entries is calculated by dividing the remaining buffer size by the attacker-controlled vprp->fields value, rather than by sizeof(gst_riff_vprp_video_field_desc). This can cause the parser to treat more field descriptors as available than fit in the input buffer, resulting in out-of-bounds reads. Processing a crafted AVI via playbin/decodebin can crash the application (denial of service). Fixed upstream in gst-plugins-good 1.28.6 (GStreamer-SA-2026-0072).","publishedAt":"2026-08-12T20:17:56","lastModifiedAt":"2026-08-19T21:17:36","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-73434","cvssScore":6.1,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H","epssProbability":0.00131,"riskScore":0.62,"affectedProduct":"gst-plugins-good","affectedVersions":"<1.28.6","vulnerabilityType":"Library","operatingSystems":["Linux"],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-73434","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-73434","en":"https://www.redsauce.net/en/cves/CVE-2026-73434","fr":"https://www.redsauce.net/fr/cves/CVE-2026-73434","pt":"https://www.redsauce.net/pt/cves/CVE-2026-73434","de":"https://www.redsauce.net/de/cves/CVE-2026-73434","sk":"https://www.redsauce.net/sk/cves/CVE-2026-73434","el":"https://www.redsauce.net/el/cves/CVE-2026-73434"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-73434"}}
