CVSS: 9.1EPSS: 1%CPEs: 28EXPL: 1CVE-2016-5114 – php: out-of-bounds write in fpm_log.c
https://notcve.org/view.php?id=CVE-2016-5114
sapi/fpm/fpm/fpm_log.c in PHP before 5.5.31, 5.6.x before 5.6.17, and 7.x before 7.0.2 misinterprets the semantics of the snprintf return value, which allows attackers to obtain sensitive information from process memory or cause a denial of service (out-of-bounds read and buffer overflow) via a long string, as demonstrated by a long URI in a configuration with custom REQUEST_URI logging. sapi/fpm/fpm/fpm_log.c en PHP en versiones anteriores a 5.5.31, 5.6.x en versiones anteriores a 5.6.17 y 7.x en versiones anteriores a 7.0.2 malinterpreta la semántica del valor de retorno snprinfg, lo que permite a atacantes remotos obtener información sensible del proceso de memoria o provocar una denegación de servicio (lectura fuera de rango y desbordamiento de búfer) a través de una cadena larga, como se demuestra por una URl larga en una configuración con inicio de sesión REQUEST_URI personalizado. An out-of-bounds write flaw was found in the fpm_log_write() logging function of PHP's FastCGI Process Manager service. A remote attacker could repeatedly send maliciously crafted requests to force FPM to exhaust file system space, creating a denial of service and preventing further logging. • http://github.com/php/php-src/commit/2721a0148649e07ed74468f097a28899741eb58f?w=1 http://php.net/ChangeLog-5.php http://php.net/ChangeLog-7.php http://rhn.redhat.com/errata/RHSA-2016-2750.html http://www.openwall.com/lists/oss-security/2016/05/29/1 http://www.search-lab.hu/about-us/news/111-some-unusual-vulnerabilities-in-the-php-engine https://bugs.php.net/bug.php?id=70755 https://h20566.www2.hpe.com/portal/site/hpsc/public/kb/docDisplay?docId=emr_na-c05240731 https& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •
