{"id":"UBUNTU-CVE-2026-90558","details":"sngrep through 1.8.4 contains stack buffer overflow vulnerabilities in SIP attribute formatting routines when header values exceed the 255-byte buffer limit. Attackers can craft malicious SIP packets with oversized Call-ID, X-Call-ID, or other header fields to overflow stack buffers and cause crashes or execute arbitrary code during packet parsing and rendering.","modified":"2026-09-16T11:44:18Z","published":"2026-09-12T18:16:00Z","upstream":["CVE-2026-90558"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-90558"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-90558"},{"type":"REPORT","url":"https://github.com/irontec/sngrep"},{"type":"REPORT","url":"https://github.com/irontec/sngrep/blob/v1.8.4/src/sip_call.c#L260"},{"type":"REPORT","url":"https://github.com/irontec/sngrep/blob/v1.8.4/src/sip_msg.c#L150"},{"type":"REPORT","url":"https://github.com/irontec/sngrep/commit/1ff74ee3ab5ff280e8ba976aa8c744dca57eb35b"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/sngrep-through-1.8.4-stack-buffer-overflow-via-sip-headers"}],"affected":[{"package":{"name":"sngrep","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/sngrep?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.4.1-1","1.0.0-1","1.1.0-1","1.2.0-1","1.2.0-1build1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.2.0-1build1","binary_name":"sngrep"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-90558.json"}},{"package":{"name":"sngrep","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/sngrep?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.4.3-1","1.4.4-1","1.4.4-2","1.4.5-1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.4.5-1","binary_name":"sngrep"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-90558.json"}},{"package":{"name":"sngrep","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/sngrep?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.4.6-1","1.4.6-2"],"ecosystem_specific":{"binaries":[{"binary_name":"sngrep","binary_version":"1.4.6-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-90558.json"}},{"package":{"name":"sngrep","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/sngrep?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.4.9-1","1.4.10-1","1.4.10-1ubuntu0.1"],"ecosystem_specific":{"binaries":[{"binary_name":"sngrep","binary_version":"1.4.10-1ubuntu0.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-90558.json"}},{"package":{"name":"sngrep","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/sngrep?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.7.0-2","1.8.0-1","1.8.0-1build1","1.8.0-1build2"],"ecosystem_specific":{"binaries":[{"binary_name":"sngrep","binary_version":"1.8.0-1build2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-90558.json"}},{"package":{"name":"sngrep","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/sngrep?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.8.2-1","1.8.3-1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.8.3-1","binary_name":"sngrep"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-90558.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"},{"type":"Ubuntu","score":"medium"}]}
