{"id":"UBUNTU-CVE-2026-48962","details":"IO::Compress versions before 2.220 for Perl can execute arbitrary code in File::GlobMapper via an attacker-controlled output glob. _parseOutputGlob() wraps the caller-supplied output glob string in double quotes and stores it in the parser state; _getFiles() then runs the stored expression through eval STRING. A literal double quote in the output glob closes the dquote wrapper, and the characters that follow are evaluated as Perl. Arbitrary Perl in the output glob executes at the calling process's privilege.","modified":"2026-09-09T19:45:03.296832490Z","published":"2026-05-27T04:16:00Z","related":["USN-8684-1"],"upstream":["CVE-2026-48962"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-48962"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-48962"},{"type":"REPORT","url":"https://lists.security.metacpan.org/cve-announce/msg/40434385/"},{"type":"REPORT","url":"https://github.com/pmqs/IO-Compress/commit/f2db247bf90d4cc7ee2710be384946081f3b4610.patch"},{"type":"REPORT","url":"https://metacpan.org/release/PMQS/IO-Compress-2.220/changes"},{"type":"REPORT","url":"http://www.openwall.com/lists/oss-security/2026/05/27/4"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-8684-1"}],"affected":[{"package":{"name":"perl","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/perl?arch=source&distro=esm-infra-legacy%2Ftrusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.14.2-21build1","5.18.1-4","5.18.1-4build1","5.18.1-5","5.18.2-2","5.18.2-2ubuntu1","5.18.2-2ubuntu1.1","5.18.2-2ubuntu1.3","5.18.2-2ubuntu1.4","5.18.2-2ubuntu1.6","5.18.2-2ubuntu1.7","5.18.2-2ubuntu1.7+esm3","5.18.2-2ubuntu1.7+esm4","5.18.2-2ubuntu1.7+esm5","5.18.2-2ubuntu1.7+esm7","5.18.2-2ubuntu1.7+esm8","5.18.2-2ubuntu1.7+esm9"],"ecosystem_specific":{"binaries":[{"binary_name":"libcgi-fast-perl","binary_version":"5.18.2-2ubuntu1.7+esm9"},{"binary_version":"5.18.2-2ubuntu1.7+esm9","binary_name":"libperl5.18"},{"binary_name":"perl","binary_version":"5.18.2-2ubuntu1.7+esm9"},{"binary_name":"perl-base","binary_version":"5.18.2-2ubuntu1.7+esm9"},{"binary_name":"perl-debug","binary_version":"5.18.2-2ubuntu1.7+esm9"},{"binary_name":"perl-modules","binary_version":"5.18.2-2ubuntu1.7+esm9"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-48962.json"}},{"package":{"name":"perl","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/perl?arch=source&distro=esm-infra-legacy%2Fxenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.20.2-6","5.22.1-3","5.22.1-4","5.22.1-5","5.22.1-7","5.22.1-8","5.22.1-9","5.22.1-9ubuntu0.2","5.22.1-9ubuntu0.3","5.22.1-9ubuntu0.5","5.22.1-9ubuntu0.6","5.22.1-9ubuntu0.9","5.22.1-9ubuntu0.9+esm1","5.22.1-9ubuntu0.9+esm2","5.22.1-9ubuntu0.9+esm3","5.22.1-9ubuntu0.9+esm4"],"ecosystem_specific":{"binaries":[{"binary_name":"libperl5.22","binary_version":"5.22.1-9ubuntu0.9+esm4"},{"binary_name":"perl","binary_version":"5.22.1-9ubuntu0.9+esm4"},{"binary_name":"perl-base","binary_version":"5.22.1-9ubuntu0.9+esm4"},{"binary_version":"5.22.1-9ubuntu0.9+esm4","binary_name":"perl-debug"},{"binary_version":"5.22.1-9ubuntu0.9+esm4","binary_name":"perl-modules-5.22"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-48962.json"}},{"package":{"name":"libio-compress-perl","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/libio-compress-perl?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.068-2","2.069-1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.069-1","binary_name":"libio-compress-perl"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-48962.json"}},{"package":{"name":"perl","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/perl?arch=source&distro=esm-infra%2Fbionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.26.0-8ubuntu1","5.26.1-2ubuntu1","5.26.1-3","5.26.1-4","5.26.1-4build1","5.26.1-5","5.26.1-6","5.26.1-6ubuntu0.1","5.26.1-6ubuntu0.2","5.26.1-6ubuntu0.3","5.26.1-6ubuntu0.5","5.26.1-6ubuntu0.6","5.26.1-6ubuntu0.7","5.26.1-6ubuntu0.7+esm2","5.26.1-6ubuntu0.7+esm3","5.26.1-6ubuntu0.7+esm4"],"ecosystem_specific":{"binaries":[{"binary_version":"5.26.1-6ubuntu0.7+esm4","binary_name":"libperl5.26"},{"binary_version":"5.26.1-6ubuntu0.7+esm4","binary_name":"perl"},{"binary_name":"perl-base","binary_version":"5.26.1-6ubuntu0.7+esm4"},{"binary_version":"5.26.1-6ubuntu0.7+esm4","binary_name":"perl-debug"},{"binary_name":"perl-modules-5.26","binary_version":"5.26.1-6ubuntu0.7+esm4"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-48962.json"}},{"package":{"name":"libio-compress-perl","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/libio-compress-perl?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.074-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libio-compress-perl","binary_version":"2.074-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-48962.json"}},{"package":{"name":"perl","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/perl?arch=source&dis
