{"id":"UBUNTU-CVE-2022-21722","details":"PJSIP is a free and open source multimedia communication library written in C language implementing standard based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. In version 2.11.1 and prior, there are various cases where it is possible that certain incoming RTP/RTCP packets can potentially cause out-of-bound read access. This issue affects all users that use PJMEDIA and accept incoming RTP/RTCP. A patch is available as a commit in the `master` branch. There are no known workarounds.","modified":"2026-04-22T15:23:13.609268Z","published":"2022-01-27T00:15:00Z","related":["USN-6422-1"],"upstream":["CVE-2022-21722"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2022-21722"},{"type":"REPORT","url":"https://github.com/pjsip/pjproject/security/advisories/GHSA-m66q-q64c-hv36"},{"type":"REPORT","url":"https://github.com/pjsip/pjproject/commit/22af44e68a0c7d190ac1e25075e1382f77e9397a"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6422-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2022-21722"}],"affected":[{"package":{"name":"pjproject","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/pjproject@2.1.0.0.ast20130823-1+deb8u1ubuntu0.1~esm1?arch=source&distro=esm-apps/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.1.0.0.ast20130823-1","2.1.0.0.ast20130823-1+deb8u1build0.16.04.1","2.1.0.0.ast20130823-1+deb8u1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.1.0.0.ast20130823-1+deb8u1ubuntu0.1~esm1","binary_name":"libpj2"},{"binary_version":"2.1.0.0.ast20130823-1+deb8u1ubuntu0.1~esm1","binary_name":"libpjlib-util2"},{"binary_version":"2.1.0.0.ast20130823-1+deb8u1ubuntu0.1~esm1","binary_name":"libpjmedia-audiodev2"},{"binary_version":"2.1.0.0.ast20130823-1+deb8u1ubuntu0.1~esm1","binary_name":"libpjmedia-codec2"},{"binary_version":"2.1.0.0.ast20130823-1+deb8u1ubuntu0.1~esm1","binary_name":"libpjmedia-videodev2"},{"binary_version":"2.1.0.0.ast20130823-1+deb8u1ubuntu0.1~esm1","binary_name":"libpjmedia2"},{"binary_version":"2.1.0.0.ast20130823-1+deb8u1ubuntu0.1~esm1","binary_name":"libpjnath2"},{"binary_version":"2.1.0.0.ast20130823-1+deb8u1ubuntu0.1~esm1","binary_name":"libpjsip-simple2"},{"binary_version":"2.1.0.0.ast20130823-1+deb8u1ubuntu0.1~esm1","binary_name":"libpjsip-ua2"},{"binary_version":"2.1.0.0.ast20130823-1+deb8u1ubuntu0.1~esm1","binary_name":"libpjsip2"},{"binary_version":"2.1.0.0.ast20130823-1+deb8u1ubuntu0.1~esm1","binary_name":"libpjsua2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-21722.json"}},{"package":{"name":"pjproject","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/pjproject@2.7.2~dfsg-1ubuntu0.1~esm1?arch=source&distro=esm-apps/bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.6~dfsg-2","2.7~dfsg-1","2.7.1~dfsg-1","2.7.1~dfsg-1build1","2.7.2~dfsg-1","2.7.2~dfsg-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.7.2~dfsg-1ubuntu0.1~esm1","binary_name":"libpj2"},{"binary_version":"2.7.2~dfsg-1ubuntu0.1~esm1","binary_name":"libpjlib-util2"},{"binary_version":"2.7.2~dfsg-1ubuntu0.1~esm1","binary_name":"libpjmedia-audiodev2"},{"binary_version":"2.7.2~dfsg-1ubuntu0.1~esm1","binary_name":"libpjmedia-codec2"},{"binary_version":"2.7.2~dfsg-1ubuntu0.1~esm1","binary_name":"libpjmedia-videodev2"},{"binary_version":"2.7.2~dfsg-1ubuntu0.1~esm1","binary_name":"libpjmedia2"},{"binary_version":"2.7.2~dfsg-1ubuntu0.1~esm1","binary_name":"libpjnath2"},{"binary_version":"2.7.2~dfsg-1ubuntu0.1~esm1","binary_name":"libpjsip-simple2"},{"binary_version":"2.7.2~dfsg-1ubuntu0.1~esm1","binary_name":"libpjsip-ua2"},{"binary_version":"2.7.2~dfsg-1ubuntu0.1~esm1","binary_name":"libpjsip2"},{"binary_version":"2.7.2~dfsg-1ubuntu0.1~esm1","binary_name":"libpjsua2"},{"binary_version":"2.7.2~dfsg-1ubuntu0.1~esm1","binary_name":"libpjsua2-2v5"},{"binary_version":"2.7.2~dfsg-1ubuntu0.1~esm1","binary_name":"python-pjproject"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-21722.json"}},{"package":{"name":"ring","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/ring@20190215.1.f152c98~ds1-1+deb10u2build0.20.04.1?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"20190215.1.f152c98~ds1-1+deb10u2build0.20.04.1"}]}],"versions":["20190215.1.f152c98~ds1-1","20190215.1.f152c98~ds1-1build1","20190215.1.f152c98~ds1-1build2"],"ecosystem_specific":{"binaries":[{"binary_version":"20190215.1.f152c98~ds1-1+deb10u2build0.20.04.1","binary_name":"jami"},{"binary_version":"20190215.1.f152c98~ds1-1+deb10u2build0.20.04.1","binary_name":"jami-daemon"},{"binary_version":"20190215.1.f152c98~ds1-1+deb10u2build0.20.04.1","binary_name":"ring"},{"binary_version":"20190215.1.f152c98~ds1-1+deb10u2build0.20.04.1","binary_name":"ring-daemon"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-21722.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
