{"id":"UBUNTU-CVE-2026-0719","details":"A flaw was identified in the NTLM authentication handling of the libsoup HTTP library, used by GNOME and other applications for network communication. When processing extremely long passwords, an internal size calculation can overflow due to improper use of signed integers. This results in incorrect memory allocation on the stack, followed by unsafe memory copying. As a result, applications using libsoup may crash unexpectedly, creating a denial-of-service risk.","modified":"2026-03-13T18:00:43.316714Z","published":"2026-01-08T13:15:00Z","upstream":["CVE-2026-0719"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-0719"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-0719"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2026-0719"}],"affected":[{"package":{"name":"libsoup2.4","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/libsoup2.4@2.52.2-1ubuntu0.3+esm5?arch=source&distro=esm-infra/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.50.0-2debian1","2.52.1-1","2.52.2-1","2.52.2-1ubuntu0.1","2.52.2-1ubuntu0.2","2.52.2-1ubuntu0.3","2.52.2-1ubuntu0.3+esm1","2.52.2-1ubuntu0.3+esm2","2.52.2-1ubuntu0.3+esm3","2.52.2-1ubuntu0.3+esm4","2.52.2-1ubuntu0.3+esm5"],"ecosystem_specific":{"binaries":[{"binary_version":"2.52.2-1ubuntu0.3+esm5","binary_name":"gir1.2-soup-2.4"},{"binary_version":"2.52.2-1ubuntu0.3+esm5","binary_name":"libsoup-gnome2.4-1"},{"binary_version":"2.52.2-1ubuntu0.3+esm5","binary_name":"libsoup-gnome2.4-dev"},{"binary_version":"2.52.2-1ubuntu0.3+esm5","binary_name":"libsoup2.4-1"},{"binary_version":"2.52.2-1ubuntu0.3+esm5","binary_name":"libsoup2.4-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-0719.json"}},{"package":{"name":"libsoup2.4","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/libsoup2.4@2.62.1-1ubuntu0.4+esm6?arch=source&distro=esm-infra/bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.60.1-1","2.60.2-1","2.60.2-2","2.60.3-1","2.61.90-1","2.62.0-1","2.62.1-1","2.62.1-1ubuntu0.1","2.62.1-1ubuntu0.3","2.62.1-1ubuntu0.4","2.62.1-1ubuntu0.4+esm1","2.62.1-1ubuntu0.4+esm2","2.62.1-1ubuntu0.4+esm3","2.62.1-1ubuntu0.4+esm4","2.62.1-1ubuntu0.4+esm5","2.62.1-1ubuntu0.4+esm6"],"ecosystem_specific":{"binaries":[{"binary_version":"2.62.1-1ubuntu0.4+esm6","binary_name":"gir1.2-soup-2.4"},{"binary_version":"2.62.1-1ubuntu0.4+esm6","binary_name":"libsoup-gnome2.4-1"},{"binary_version":"2.62.1-1ubuntu0.4+esm6","binary_name":"libsoup-gnome2.4-dev"},{"binary_version":"2.62.1-1ubuntu0.4+esm6","binary_name":"libsoup2.4-1"},{"binary_version":"2.62.1-1ubuntu0.4+esm6","binary_name":"libsoup2.4-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-0719.json"}},{"package":{"name":"libsoup2.4","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/libsoup2.4@2.70.0-1ubuntu0.5+esm1?arch=source&distro=esm-infra/focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.68.2-0ubuntu1","2.68.2-1","2.68.2-2","2.68.2-2build2","2.69.90-1","2.70.0-1","2.70.0-1ubuntu0.1","2.70.0-1ubuntu0.2","2.70.0-1ubuntu0.3","2.70.0-1ubuntu0.4","2.70.0-1ubuntu0.5","2.70.0-1ubuntu0.5+esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.70.0-1ubuntu0.5+esm1","binary_name":"gir1.2-soup-2.4"},{"binary_version":"2.70.0-1ubuntu0.5+esm1","binary_name":"libsoup-gnome2.4-1"},{"binary_version":"2.70.0-1ubuntu0.5+esm1","binary_name":"libsoup-gnome2.4-dev"},{"binary_version":"2.70.0-1ubuntu0.5+esm1","binary_name":"libsoup2.4-1"},{"binary_version":"2.70.0-1ubuntu0.5+esm1","binary_name":"libsoup2.4-dev"},{"binary_version":"2.70.0-1ubuntu0.5+esm1","binary_name":"libsoup2.4-tests"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-0719.json"}},{"package":{"name":"libsoup2.4","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/libsoup2.4@2.74.2-3ubuntu0.6?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.72.0-3ubuntu3","2.74.1-1","2.74.2-2","2.74.2-3","2.74.2-3ubuntu0.1","2.74.2-3ubuntu0.2","2.74.2-3ubuntu0.3","2.74.2-3ubuntu0.4","2.74.2-3ubuntu0.5","2.74.2-3ubuntu0.6"],"ecosystem_specific":{"binaries":[{"binary_version":"2.74.2-3ubuntu0.6","binary_name":"gir1.2-soup-2.4"},{"binary_version":"2.74.2-3ubuntu0.6","binary_name":"libsoup-gnome2.4-1"},{"binary_version":"2.74.2-3ubuntu0.6","binary_name":"libsoup-gnome2.4-dev"},{"binary_version":"2.74.2-3ubuntu0.6","binary_name":"libsoup2.4-1"},{"binary_version":"2.74.2-3ubuntu0.6","binary_name":"libsoup2.4-common"},{"binary_version":"2.74.2-3ubuntu0.6","binary_name":"libsoup2.4-dev"},{"binary_version":"2.74.2-3ubuntu0.6","binary_name":"libsoup2.4-tests"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-0719.json"}},{"package":{"name":"libsoup3","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/libsoup3@3.0.7-0ubuntu1+esm7?arch=source&distro=esm-apps/jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.0.4-2","3.0.4-3","3.0.5-1","3.0.7-0ubuntu1","3.0.7-0ubuntu1+esm1","3.0.7-0ubuntu1+esm2","3.0.7-0ubuntu1+esm3","3.0.7-0ubuntu1+esm4","3.0.7-0ubuntu1+esm5","3.0.7-0ubuntu1+esm6
