CVSS: 5.9EPSS: 1%CPEs: 6EXPL: 0CVE-2018-1302 – httpd: Use-after-free on HTTP/2 stream shutdown
https://notcve.org/view.php?id=CVE-2018-1302
When an HTTP/2 stream was destroyed after being handled, the Apache HTTP Server prior to version 2.4.30 could have written a NULL pointer potentially to an already freed memory. The memory pools maintained by the server make this vulnerability hard to trigger in usual configurations, the reporter and the team could not reproduce it outside debug builds, so it is classified as low risk. Cuando un flujo de datos o stream HTTP/2 se destruye después de haber sido manipulado, el servidor Apache HTTP en versiones anteriores a la 2.4.30 podría escribir un puntero NULL en una memoria ya liberada. Los bloques de memoria mantenidos por el servidor hacen que sea difícil que esta vulnerabilidad tenga lugar en configuraciones normales, el informador y el equipo no podían reproducirla fuera de builds de depuración, por lo que se clasifica como de riesgo bajo. • http://www.openwall.com/lists/oss-security/2018/03/24/5 http://www.securityfocus.com/bid/103528 http://www.securitytracker.com/id/1040567 https://access.redhat.com/errata/RHSA-2019:0366 https://access.redhat.com/errata/RHSA-2019:0367 https://httpd.apache.org/security/vulnerabilities_24.html https://lists.apache.org/thread.html/56c2e7cc9deb1c12a843d0dc251ea7fd3e7e80293cde02fcd65286ba%40%3Ccvs.httpd.apache.org%3E https://lists.apache.org/thread.html/84a3714f0878781f6ed84473d1a503d2cc382277e100450209231830%40%3Ccvs.httpd& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-476: NULL Pointer Dereference •
CVSS: 5.9EPSS: 1%CPEs: 18EXPL: 0CVE-2018-1301 – httpd: Out of bounds access after failure in reading the HTTP request
https://notcve.org/view.php?id=CVE-2018-1301
A specially crafted request could have crashed the Apache HTTP Server prior to version 2.4.30, due to an out of bound access after a size limit is reached by reading the HTTP header. This vulnerability is considered very hard if not impossible to trigger in non-debug mode (both log and build level), so it is classified as low risk for common server usage. Una petición especialmente manipulada podría haber provocado el cierre inesperado del servidor Apache HTTP en versiones anteriores a la 2.4.30, debido a un acceso fuera de límites tras alcanzar un límite de tamaño mediante la lectura de una cabecera HTTP. Esta vulnerabilidad se considera crítica si no es imposible desencadenarla en un modo que no sea de depuración (tanto a nivel de log como de build), por lo que se clasifica como vulnerabilidad de riesgo bajo para un uso común del servidor. • http://www.openwall.com/lists/oss-security/2018/03/24/2 http://www.securityfocus.com/bid/103515 http://www.securitytracker.com/id/1040573 https://access.redhat.com/errata/RHSA-2018:3558 https://access.redhat.com/errata/RHSA-2019:0366 https://access.redhat.com/errata/RHSA-2019:0367 https://httpd.apache.org/security/vulnerabilities_24.html https://lists.apache.org/thread.html/56c2e7cc9deb1c12a843d0dc251ea7fd3e7e80293cde02fcd65286ba%40%3Ccvs.httpd.apache.org%3E https://lists.apache.org/thread.ht • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •

CVSS: 7.5EPSS: 97%CPEs: 22EXPL: 6CVE-2017-9798 – Apache < 2.2.34 / < 2.4.27 - OPTIONS Memory Leak
https://notcve.org/view.php?id=CVE-2017-9798
Apache httpd allows remote attackers to read secret data from process memory if the Limit directive can be set in a user's .htaccess file, or if httpd.conf has certain misconfigurations, aka Optionsbleed. This affects the Apache HTTP Server through 2.2.34 and 2.4.x through 2.4.27. The attacker sends an unauthenticated OPTIONS HTTP request when attempting to read secret data. This is a use-after-free issue and thus secret data is not always sent, and the specific data depends on many factors including configuration. Exploitation with .htaccess can be blocked with a patch to the ap_limit_section function in server/core.c. • https://www.exploit-db.com/exploits/42745 https://github.com/nitrado/CVE-2017-9798 https://github.com/l0n3rs/CVE-2017-9798 http://openwall.com/lists/oss-security/2017/09/18/2 http://www.debian.org/security/2017/dsa-3980 http://www.oracle.com/technetwork/security-advisory/cpuapr2018-3678067.html http://www.oracle.com/technetwork/security-advisory/cpujan2018-3236628.html http://www.oracle.com/technetwork/security-advisory/cpujul2018-4258247.html http://www.oracle.com/technetwork/securi • CWE-416: Use After Free •
