{"id":"UBUNTU-CVE-2026-111130","details":"OpenSlide through 4.0.1 contains a heap out-of-bounds read vulnerability in the MIRAX reader that allows attackers to read past the slide_positions array via crafted Slidedat.ini values. Attackers can supply a MIRAX slide whose CameraImageDivisionsPerSide does not evenly divide the image counts, crashing applications that open it and corrupting tile geometry.","modified":"2026-10-17T12:59:52.453718931Z","published":"2026-10-16T00:00:00Z","upstream":["CVE-2026-111130"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-111130"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-111130"},{"type":"REPORT","url":"https://github.com/openslide/openslide"},{"type":"REPORT","url":"https://github.com/openslide/openslide/blob/fe79a9713bef2bfd64bbfefd15704060764b1274/src/openslide-vendor-mirax.c#L1033-L1034"},{"type":"REPORT","url":"https://github.com/openslide/openslide/blob/fe79a9713bef2bfd64bbfefd15704060764b1274/src/openslide-vendor-mirax.c#L611-L635"},{"type":"REPORT","url":"https://hackmd.io/@haind-pwn/openslide-mirax-slide-position-index-oob-read"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/openslide-through-4.0.1-heap-out-of-bounds-read-via-mirax-get-tile-position"}],"affected":[{"package":{"name":"openslide","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/openslide?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.4.0-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libopenslide0","binary_version":"3.4.0-1build1"},{"binary_version":"3.4.0-1build1","binary_name":"openslide-tools"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111130.json"}},{"package":{"name":"openslide","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/openslide?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.4.1+dfsg-2"],"ecosystem_specific":{"binaries":[{"binary_name":"libopenslide0","binary_version":"3.4.1+dfsg-2"},{"binary_version":"3.4.1+dfsg-2","binary_name":"openslide-tools"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111130.json"}},{"package":{"name":"openslide","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/openslide?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.4.1+dfsg-4"],"ecosystem_specific":{"binaries":[{"binary_version":"3.4.1+dfsg-4","binary_name":"libopenslide0"},{"binary_version":"3.4.1+dfsg-4","binary_name":"openslide-tools"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111130.json"}},{"package":{"name":"openslide","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/openslide?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.4.1+dfsg-5","3.4.1+dfsg-5build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libopenslide0","binary_version":"3.4.1+dfsg-5build1"},{"binary_version":"3.4.1+dfsg-5build1","binary_name":"openslide-tools"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111130.json"}},{"package":{"name":"openslide","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/openslide?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.4.1+dfsg-6build1","3.4.1+dfsg-7","3.4.1+dfsg-7build1","3.4.1+dfsg-7build2"],"ecosystem_specific":{"binaries":[{"binary_version":"3.4.1+dfsg-7build2","binary_name":"libopenslide0"},{"binary_name":"openslide-tools","binary_version":"3.4.1+dfsg-7build2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111130.json"}},{"package":{"name":"openslide","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/openslide?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.4.1+dfsg-7build4","3.4.1+dfsg-9"],"ecosystem_specific":{"binaries":[{"binary_version":"3.4.1+dfsg-9","binary_name":"libopenslide0"},{"binary_name":"openslide-tools","binary_version":"3.4.1+dfsg-9"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111130.json"}},{"package":{"name":"openslide","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/openslide?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.4.1+dfsg-7build3","3.4.1+dfsg-7build4"],"ecosystem_specific":{"binaries":[{"binary_name":"libopenslide0","binary_version":"3.4.1+dfsg-7build4"},{"binary_name":"openslide-tools","binary_version":"3.4.1+dfsg-7build4"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111130.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:L/I:N/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N"},{"type":"Ubuntu","score":"medium"}]}
