{"id":"UBUNTU-CVE-2026-110658","details":"Sofia-SIP through 1.13.18 contains a heap out-of-bounds read vulnerability in msg_multipart_parse() that allows unauthenticated remote attackers to crash the process by sending oversized MIME boundaries. Attackers can send an INVITE with a multipart Content-Type whose boundary exceeds the body length, causing memcmp to read past the heap buffer and crash the process.","modified":"2026-10-17T12:58:03.768530380Z","published":"2026-10-15T00:00:00Z","upstream":["CVE-2026-110658"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-110658"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-110658"},{"type":"REPORT","url":"https://github.com/freeswitch/sofia-sip"},{"type":"REPORT","url":"https://github.com/freeswitch/sofia-sip/blob/ad36ac8f755308e8b87f98a505e83d4e408e5cc3/libsofia-sip-ua/msg/msg_mime.c#L404"},{"type":"REPORT","url":"https://hackmd.io/@haind-pwn/sofia-sip-multipart-oob-read"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/sofia-sip-through-1.13.18-heap-out-of-bounds-read-via-msg-multipart-parse"}],"affected":[{"package":{"name":"sofia-sip","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/sofia-sip?arch=source&distro=esm-apps%2Fxenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.12.11+20110422.1-2ubuntu1","1.12.11+20110422.1-2.1+deb10u3ubuntu0.16.04.1~esm1","1.12.11+20110422.1-2.1+deb10u3ubuntu0.16.04.1~esm2"],"ecosystem_specific":{"binaries":[{"binary_name":"libsofia-sip-ua-glib3","binary_version":"1.12.11+20110422.1-2.1+deb10u3ubuntu0.16.04.1~esm2"},{"binary_version":"1.12.11+20110422.1-2.1+deb10u3ubuntu0.16.04.1~esm2","binary_name":"libsofia-sip-ua0"},{"binary_name":"sofia-sip-bin","binary_version":"1.12.11+20110422.1-2.1+deb10u3ubuntu0.16.04.1~esm2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-110658.json"}},{"package":{"name":"sofia-sip","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/sofia-sip?arch=source&distro=esm-apps%2Fbionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.12.11+20110422.1-2.1","1.12.11+20110422.1-2.1build1","1.12.11+20110422.1-2.1+deb10u3build0.18.04.1","1.12.11+20110422.1-2.1+deb10u3ubuntu0.18.04.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"libsofia-sip-ua-glib3","binary_version":"1.12.11+20110422.1-2.1+deb10u3ubuntu0.18.04.1~esm1"},{"binary_name":"libsofia-sip-ua0","binary_version":"1.12.11+20110422.1-2.1+deb10u3ubuntu0.18.04.1~esm1"},{"binary_version":"1.12.11+20110422.1-2.1+deb10u3ubuntu0.18.04.1~esm1","binary_name":"sofia-sip-bin"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-110658.json"}},{"package":{"name":"sofia-sip","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/sofia-sip?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.12.11+20110422.1-2.1build1","1.12.11+20110422.1-2.1+deb10u3ubuntu0.20.04.1","1.12.11+20110422.1-2.1+deb10u3ubuntu0.20.04.2"],"ecosystem_specific":{"binaries":[{"binary_name":"libsofia-sip-ua-glib3","binary_version":"1.12.11+20110422.1-2.1+deb10u3ubuntu0.20.04.2"},{"binary_name":"libsofia-sip-ua0","binary_version":"1.12.11+20110422.1-2.1+deb10u3ubuntu0.20.04.2"},{"binary_version":"1.12.11+20110422.1-2.1+deb10u3ubuntu0.20.04.2","binary_name":"sofia-sip-bin"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-110658.json"}},{"package":{"name":"sofia-sip","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/sofia-sip?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.12.11+20110422.1-2.1ubuntu1","1.12.11+20110422.1-2.1ubuntu2","1.12.11+20110422.1-2.1+deb10u3ubuntu0.22.04.1","1.12.11+20110422.1-2.1+deb10u3ubuntu0.22.04.2"],"ecosystem_specific":{"binaries":[{"binary_name":"libsofia-sip-ua-glib3","binary_version":"1.12.11+20110422.1-2.1+deb10u3ubuntu0.22.04.2"},{"binary_name":"libsofia-sip-ua0","binary_version":"1.12.11+20110422.1-2.1+deb10u3ubuntu0.22.04.2"},{"binary_version":"1.12.11+20110422.1-2.1+deb10u3ubuntu0.22.04.2","binary_name":"sofia-sip-bin"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-110658.json"}},{"package":{"name":"sofia-sip","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/sofia-sip?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.12.11+20110422.1+1e14eea~dfsg-4ubuntu1","1.12.11+20110422.1+1e14eea~dfsg-4ubuntu2","1.12.11+20110422.1+1e14eea~dfsg-6","1.12.11+20110422.1+1e14eea~dfsg-6.1build1","1.12.11+20110422.1+1e14eea~dfsg-6.1build2"],"ecosystem_specific":{"binaries":[{"binary_version":"1.12.11+20110422.1+1e14eea~dfsg-6.1build2","binary_name":"libsofia-sip-ua-glib3t64"},{"binary_name":"libsofia-sip-ua0t64","binary_version":"1.12.11+20110422.1+1e14eea~dfsg-6.1build2"},{"binary_name":"sofia-sip-bin","binary_version":"1.12.11+20110422.1+1e14eea~dfsg-6.1build2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-110658.json"}},{"package":{"name":"sofia-sip","ecosystem":"Ubuntu:26.10","purl
