{"id":"UBUNTU-CVE-2026-107373","details":"ExtUtils::Typemaps::STL::String versions before 1.06 for Perl T_STD_STRING typemap may read the SV length before stringifying the argument. The typemap uses $var = std::string( SvPV_nolen($arg), SvCUR($arg) ) However, evaluation order for C++ arguments is not specified, and some compilers may produce code that evalutes SvCUR($arg) first. When $arg is not a string (for example, an interger, number or a reference) then SvCUR will return an invalid value, and the program may abort or segfault.","modified":"2026-10-12T14:21:12.183840440Z","published":"2026-10-12T00:00:00Z","upstream":["CVE-2026-107373"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-107373"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-107373"},{"type":"REPORT","url":"cpan.org/modules"},{"type":"REPORT","url":"github.com/tsee/extutils-typemap-default"},{"type":"REPORT","url":"github.com/tsee/extutils-typemap-default/commit/a6b9c298b34ddadc582961403e715d292f82a22d"},{"type":"REPORT","url":"https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1150541"},{"type":"REPORT","url":"lists.security.metacpan.org/cve-announce/msg/44245994"},{"type":"REPORT","url":"rt.cpan.org/public/bug/display.html?id=94110"},{"type":"REPORT","url":"security-tracker.debian.org/tracker/cve-2026-107373"}],"affected":[{"package":{"name":"libextutils-typemaps-default-perl","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/libextutils-typemaps-default-perl?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.05-2"],"ecosystem_specific":{"priority_reason":"Local crash in Perl XS code when non-string values are passed through the affected typemap; no remote/default exposure.","binaries":[{"binary_name":"libextutils-typemaps-default-perl","binary_version":"1.05-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-107373.json"}},{"package":{"name":"libextutils-typemaps-default-perl","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/libextutils-typemaps-default-perl?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.05-2"],"ecosystem_specific":{"priority_reason":"Local crash in Perl XS code when non-string values are passed through the affected typemap; no remote/default exposure.","binaries":[{"binary_version":"1.05-2","binary_name":"libextutils-typemaps-default-perl"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-107373.json"}},{"package":{"name":"libextutils-typemaps-default-perl","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/libextutils-typemaps-default-perl?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.05-2"],"ecosystem_specific":{"binaries":[{"binary_version":"1.05-2","binary_name":"libextutils-typemaps-default-perl"}],"priority_reason":"Local crash in Perl XS code when non-string values are passed through the affected typemap; no remote/default exposure."},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-107373.json"}},{"package":{"name":"libextutils-typemaps-default-perl","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/libextutils-typemaps-default-perl?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.05-2.1"],"ecosystem_specific":{"binaries":[{"binary_name":"libextutils-typemaps-default-perl","binary_version":"1.05-2.1"}],"priority_reason":"Local crash in Perl XS code when non-string values are passed through the affected typemap; no remote/default exposure."},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-107373.json"}},{"package":{"name":"libextutils-typemaps-default-perl","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/libextutils-typemaps-default-perl?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.05-5"],"ecosystem_specific":{"binaries":[{"binary_name":"libextutils-typemaps-default-perl","binary_version":"1.05-5"}],"priority_reason":"Local crash in Perl XS code when non-string values are passed through the affected typemap; no remote/default exposure."},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-107373.json"}},{"package":{"name":"libextutils-typemaps-default-perl","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/libextutils-typemaps-default-perl?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.05-5"],"ecosystem_specific":{"priority_reason":"Local crash in Perl XS code when non-string values are passed through the affected typemap; no remote/default exposure.","binaries":[{"binary_name":"libextutils-typemaps-default-perl","binary_version":"1.05-5"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-107373.json"}}],"schema_version":"1.9.0","severity":[{"type":"Ubuntu","score":"low"}]}
