{"id":"DEBIAN-CVE-2026-53877","details":"An issue was discovered in Django 6.0 before 6.0.7 and 5.2 before 5.2.16. `django.contrib.gis.gdal.GDALRaster` over-reads its in-memory buffer when constructed from a bytes object, which can disclose adjacent memory or cause service degradation via a potential segmentation fault when the `vsi_buffer` property is accessed. Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected. Django would like to thank Bence Nagy for reporting this issue.","modified":"2026-09-01T16:06:50.553840179Z","published":"2026-07-07T15:16:48.453Z","upstream":["CVE-2026-53877"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-53877"}],"affected":[{"package":{"name":"python-django","ecosystem":"Debian:12","purl":"pkg:deb/debian/python-django?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3:3.2.19-1","3:3.2.19-1+deb12u1","3:3.2.19-1+deb12u1~bpo11+1","3:3.2.19-1+deb12u2","3:3.2.20-1","3:3.2.20-1.1","3:3.2.21-1","3:3.2.25-0+deb12u1","3:3.2.25-0+deb12u2","3:3.2.25-0+deb12u3","3:3.2.25-0+deb12u4","3:4.1-1","3:4.1.1-1","3:4.1.2-1","3:4.1.3-1","3:4.1.4-1","3:4.1.5-1","3:4.2-1","3:4.2.1-1","3:4.2.10-1","3:4.2.11-1","3:4.2.13-1","3:4.2.14-1","3:4.2.15-1","3:4.2.15-1~bpo12+1","3:4.2.16-1","3:4.2.17-1","3:4.2.17-2","3:4.2.18-1","3:4.2.18-1~bpo12+1","3:4.2.19-1","3:4.2.19-1~bpo12+1","3:4.2.2-1","3:4.2.20-1","3:4.2.20-1~bpo12+1","3:4.2.21-1","3:4.2.21-1~bpo12+1","3:4.2.22-1","3:4.2.23-1","3:4.2.24-1","3:4.2.25-1","3:4.2.25-2","3:4.2.26-1","3:4.2.27-1","3:4.2.27-2","3:4.2.28-1","3:4.2.29-1","3:4.2.3-1","3:4.2.30-1","3:4.2.4-1","3:4.2.5-1","3:4.2.5-2","3:4.2.6-1","3:4.2.8-1","3:4.2.9-1","3:4.2~alpha1-1","3:4.2~beta1-1","3:4.2~rc1-1","3:5.0-1","3:5.0.1-1","3:5.0.2-1","3:5.0.3-1","3:5.0.4-1","3:5.0.6-1","3:5.0~alpha1-1","3:5.0~rc1-1","3:5.1-1","3:5.1.1-1","3:5.1.2-1","3:5.1.3-1","3:5.1.4-1","3:5.1.5-1","3:5.1~alpha1-1","3:5.1~beta1-1","3:5.1~rc1-1","3:5.2-1","3:5.2.1-1","3:5.2.13-1","3:5.2.14-1","3:5.2.14-2","3:5.2.15-1","3:5.2.15-2","3:5.2.15-2~bpo13+1","3:5.2.16-1","3:5.2.16-1~bpo13+1","3:5.2.17-1","3:5.2.17-2","3:5.2.2-1","3:5.2.3-1","3:5.2.4-1","3:5.2.5-1","3:5.2.6-1","3:5.2~alpha1-1","3:5.2~beta1-1","3:5.2~rc1-1","3:6.0-1","3:6.0.1-1","3:6.0.2-1","3:6.0.3-1","3:6.0.4-1","3:6.0.5-1","3:6.0.6-1","3:6.0~alpha1-1","3:6.0~beta1-1","3:6.0~rc1-1","3:6.1-1","3:6.1~beta1-1","3:6.1~rc1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-53877.json"}},{"package":{"name":"python-django","ecosystem":"Debian:13","purl":"pkg:deb/debian/python-django?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3:4.2.23-1","3:4.2.24-1","3:4.2.25-1","3:4.2.25-2","3:4.2.26-1","3:4.2.27-0+deb13u1","3:4.2.27-1","3:4.2.27-2","3:4.2.28-0+deb13u1","3:4.2.28-0+deb13u2","3:4.2.28-1","3:4.2.29-1","3:4.2.30-1","3:5.0-1","3:5.0.1-1","3:5.0.2-1","3:5.0.3-1","3:5.0.4-1","3:5.0.6-1","3:5.0~alpha1-1","3:5.0~rc1-1","3:5.1-1","3:5.1.1-1","3:5.1.2-1","3:5.1.3-1","3:5.1.4-1","3:5.1.5-1","3:5.1~alpha1-1","3:5.1~beta1-1","3:5.1~rc1-1","3:5.2-1","3:5.2.1-1","3:5.2.13-1","3:5.2.14-1","3:5.2.14-2","3:5.2.15-1","3:5.2.15-2","3:5.2.15-2~bpo13+1","3:5.2.16-1","3:5.2.16-1~bpo13+1","3:5.2.17-1","3:5.2.17-2","3:5.2.2-1","3:5.2.3-1","3:5.2.4-1","3:5.2.5-1","3:5.2.6-1","3:5.2~alpha1-1","3:5.2~beta1-1","3:5.2~rc1-1","3:6.0-1","3:6.0.1-1","3:6.0.2-1","3:6.0.3-1","3:6.0.4-1","3:6.0.5-1","3:6.0.6-1","3:6.0~alpha1-1","3:6.0~beta1-1","3:6.0~rc1-1","3:6.1-1","3:6.1~beta1-1","3:6.1~rc1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-53877.json"}},{"package":{"name":"python-django","ecosystem":"Debian:14","purl":"pkg:deb/debian/python-django?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3:5.2.16-1"}]}],"versions":["3:4.2.23-1","3:4.2.24-1","3:4.2.25-1","3:4.2.25-2","3:4.2.26-1","3:4.2.27-1","3:4.2.27-2","3:4.2.28-1","3:4.2.29-1","3:4.2.30-1","3:5.0-1","3:5.0.1-1","3:5.0.2-1","3:5.0.3-1","3:5.0.4-1","3:5.0.6-1","3:5.0~alpha1-1","3:5.0~rc1-1","3:5.1-1","3:5.1.1-1","3:5.1.2-1","3:5.1.3-1","3:5.1.4-1","3:5.1.5-1","3:5.1~alpha1-1","3:5.1~beta1-1","3:5.1~rc1-1","3:5.2-1","3:5.2.1-1","3:5.2.13-1","3:5.2.14-1","3:5.2.14-2","3:5.2.15-1","3:5.2.15-2","3:5.2.15-2~bpo13+1","3:5.2.16-1~bpo13+1","3:5.2.2-1","3:5.2.3-1","3:5.2.4-1","3:5.2.5-1","3:5.2.6-1","3:5.2~alpha1-1","3:5.2~beta1-1","3:5.2~rc1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-53877.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
