{"id":"UBUNTU-CVE-2017-7963","details":"The GNU Multiple Precision Arithmetic Library (GMP) interfaces for PHP through 7.1.4 allow attackers to cause a denial of service (memory consumption and application crash) via operations on long strings. NOTE: the vendor disputes this, stating \"There is no security issue here, because GMP safely aborts in case of an OOM condition. The only attack vector here is denial of service. However, if you allow attacker-controlled, unbounded allocations you have a DoS vector regardless of GMP's OOM behavior.","modified":"2026-04-22T11:34:22.545787Z","published":"2017-04-19T15:59:00Z","upstream":["CVE-2017-7963"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2017-7963"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2017-7963"}],"affected":[{"package":{"name":"php5","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/php5@5.5.9+dfsg-1ubuntu4.29+esm16?arch=source&distro=esm-infra-legacy/trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.5.3+dfsg-1ubuntu2","5.5.3+dfsg-1ubuntu3","5.5.6+dfsg-1ubuntu1","5.5.6+dfsg-1ubuntu2","5.5.8+dfsg-2ubuntu1","5.5.9+dfsg-1ubuntu1","5.5.9+dfsg-1ubuntu2","5.5.9+dfsg-1ubuntu3","5.5.9+dfsg-1ubuntu4","5.5.9+dfsg-1ubuntu4.1","5.5.9+dfsg-1ubuntu4.2","5.5.9+dfsg-1ubuntu4.3","5.5.9+dfsg-1ubuntu4.4","5.5.9+dfsg-1ubuntu4.5","5.5.9+dfsg-1ubuntu4.6","5.5.9+dfsg-1ubuntu4.7","5.5.9+dfsg-1ubuntu4.9","5.5.9+dfsg-1ubuntu4.11","5.5.9+dfsg-1ubuntu4.12","5.5.9+dfsg-1ubuntu4.13","5.5.9+dfsg-1ubuntu4.14","5.5.9+dfsg-1ubuntu4.16","5.5.9+dfsg-1ubuntu4.17","5.5.9+dfsg-1ubuntu4.19","5.5.9+dfsg-1ubuntu4.20","5.5.9+dfsg-1ubuntu4.21","5.5.9+dfsg-1ubuntu4.22","5.5.9+dfsg-1ubuntu4.23","5.5.9+dfsg-1ubuntu4.24","5.5.9+dfsg-1ubuntu4.25","5.5.9+dfsg-1ubuntu4.26","5.5.9+dfsg-1ubuntu4.27","5.5.9+dfsg-1ubuntu4.29","5.5.9+dfsg-1ubuntu4.29+esm1","5.5.9+dfsg-1ubuntu4.29+esm2","5.5.9+dfsg-1ubuntu4.29+esm3","5.5.9+dfsg-1ubuntu4.29+esm4","5.5.9+dfsg-1ubuntu4.29+esm5","5.5.9+dfsg-1ubuntu4.29+esm6","5.5.9+dfsg-1ubuntu4.29+esm8","5.5.9+dfsg-1ubuntu4.29+esm10","5.5.9+dfsg-1ubuntu4.29+esm11","5.5.9+dfsg-1ubuntu4.29+esm12","5.5.9+dfsg-1ubuntu4.29+esm13","5.5.9+dfsg-1ubuntu4.29+esm14","5.5.9+dfsg-1ubuntu4.29+esm15","5.5.9+dfsg-1ubuntu4.29+esm16"],"ecosystem_specific":{"binaries":[{"binary_name":"libapache2-mod-php5","binary_version":"5.5.9+dfsg-1ubuntu4.29+esm16"},{"binary_name":"libapache2-mod-php5filter","binary_version":"5.5.9+dfsg-1ubuntu4.29+esm16"},{"binary_name":"libphp5-embed","binary_version":"5.5.9+dfsg-1ubuntu4.29+esm16"},{"binary_name":"php-pear","binary_version":"5.5.9+dfsg-1ubuntu4.29+esm16"},{"binary_name":"php5","binary_version":"5.5.9+dfsg-1ubuntu4.29+esm16"},{"binary_name":"php5-cgi","binary_version":"5.5.9+dfsg-1ubuntu4.29+esm16"},{"binary_version":"5.5.9+dfsg-1ubuntu4.29+esm16","binary_name":"php5-cli"},{"binary_name":"php5-common","binary_version":"5.5.9+dfsg-1ubuntu4.29+esm16"},{"binary_name":"php5-curl","binary_version":"5.5.9+dfsg-1ubuntu4.29+esm16"},{"binary_name":"php5-enchant","binary_version":"5.5.9+dfsg-1ubuntu4.29+esm16"},{"binary_name":"php5-fpm","binary_version":"5.5.9+dfsg-1ubuntu4.29+esm16"},{"binary_name":"php5-gd","binary_version":"5.5.9+dfsg-1ubuntu4.29+esm16"},{"binary_name":"php5-gmp","binary_version":"5.5.9+dfsg-1ubuntu4.29+esm16"},{"binary_name":"php5-intl","binary_version":"5.5.9+dfsg-1ubuntu4.29+esm16"},{"binary_name":"php5-ldap","binary_version":"5.5.9+dfsg-1ubuntu4.29+esm16"},{"binary_name":"php5-mysql","binary_version":"5.5.9+dfsg-1ubuntu4.29+esm16"},{"binary_name":"php5-mysqlnd","binary_version":"5.5.9+dfsg-1ubuntu4.29+esm16"},{"binary_name":"php5-odbc","binary_version":"5.5.9+dfsg-1ubuntu4.29+esm16"},{"binary_name":"php5-pgsql","binary_version":"5.5.9+dfsg-1ubuntu4.29+esm16"},{"binary_name":"php5-pspell","binary_version":"5.5.9+dfsg-1ubuntu4.29+esm16"},{"binary_name":"php5-readline","binary_version":"5.5.9+dfsg-1ubuntu4.29+esm16"},{"binary_name":"php5-recode","binary_version":"5.5.9+dfsg-1ubuntu4.29+esm16"},{"binary_name":"php5-snmp","binary_version":"5.5.9+dfsg-1ubuntu4.29+esm16"},{"binary_name":"php5-sqlite","binary_version":"5.5.9+dfsg-1ubuntu4.29+esm16"},{"binary_name":"php5-sybase","binary_version":"5.5.9+dfsg-1ubuntu4.29+esm16"},{"binary_name":"php5-tidy","binary_version":"5.5.9+dfsg-1ubuntu4.29+esm16"},{"binary_name":"php5-xmlrpc","binary_version":"5.5.9+dfsg-1ubuntu4.29+esm16"},{"binary_name":"php5-xsl","binary_version":"5.5.9+dfsg-1ubuntu4.29+esm16"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2017/UBUNTU-CVE-2017-7963.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"low"}]}
