CVE-2017-9788 – httpd: Uninitialized memory reflection in mod_auth_digest
https://notcve.org/view.php?id=CVE-2017-9788
In Apache httpd before 2.2.34 and 2.4.x before 2.4.27, the value placeholder in [Proxy-]Authorization headers of type 'Digest' was not initialized or reset before or between successive key=value assignments by mod_auth_digest. Providing an initial key with no '=' assignment could reflect the stale value of uninitialized pool memory used by the prior request, leading to leakage of potentially confidential information, and a segfault in other cases resulting in denial of service. En Apache httpd, en versiones anteriores a la 2.2.34 y en versiones 2.4.x anteriores a la 2.4.27, el valor placeholder en cabeceras [Proxy-]Authorization del tipo 'Digest' no se inicializó o reinició antes de o entre las asignaciones sucesivas key=value por mod_auth_digest. Proporcionar una clave inicial sin asignación "=" podría reflejar el valor obsoleto de la memoria agrupada no inicializada utilizada por la petición anterior. Esto podría dar lugar al filtrado de información potencialmente confidencial y, en otros casos, a un fallo de segmentación que daría como resultado una denegación de servicio (DoS) It was discovered that the httpd's mod_auth_digest module did not properly initialize memory before using it when processing certain headers related to digest authentication. • http://www.debian.org/security/2017/dsa-3913 http://www.oracle.com/technetwork/security-advisory/cpuoct2017-3236626.html http://www.securityfocus.com/bid/99569 http://www.securitytracker.com/id/1038906 https://access.redhat.com/errata/RHSA-2017:2478 https://access.redhat.com/errata/RHSA-2017:2479 https://access.redhat.com/errata/RHSA-2017:2483 https://access.redhat.com/errata/RHSA-2017:2708 https://access.redhat.com/errata/RHSA-2017:2709 https://access.redhat.com/errata/RHS • CWE-20: Improper Input Validation CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-456: Missing Initialization of a Variable •
CVE-2017-5645 – log4j: Socket receiver deserialization vulnerability
https://notcve.org/view.php?id=CVE-2017-5645
In Apache Log4j 2.x before 2.8.2, when using the TCP socket server or UDP socket server to receive serialized log events from another application, a specially crafted binary payload can be sent that, when deserialized, can execute arbitrary code. En Apache Log4j 2.x en versiones anteriores a 2.8.2, cuando se utiliza el servidor de socket TCP o el servidor de socket UDP para recibir sucesos de registro serializados de otra aplicación, puede enviarse una carga binaria especialmente diseñada que, cuando se deserializa, puede ejecutar código arbitrario. It was found that when using remote logging with log4j socket server the log4j server would deserialize any log event received via TCP or UDP. An attacker could use this flaw to send a specially crafted log event that, during deserialization, would execute arbitrary code in the context of the logger application. • https://github.com/pimps/CVE-2017-5645 http://www.openwall.com/lists/oss-security/2019/12/19/2 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/security-advisory/cpuoct2018-4428296.html http://www.securityfocus.com/bid/97702 http://www.securitytracker.com/id/1040200 http://www.securit • CWE-502: Deserialization of Untrusted Data •
CVE-2018-6485 – glibc: Integer overflow in posix_memalign in memalign functions
https://notcve.org/view.php?id=CVE-2018-6485
An integer overflow in the implementation of the posix_memalign in memalign functions in the GNU C Library (aka glibc or libc6) 2.26 and earlier could cause these functions to return a pointer to a heap area that is too small, potentially leading to heap corruption. Un desbordamiento de enteros en la implementación de posix_memalign en las funciones memalign en GNU C Library (también conocido como glibc o libc6) en versiones 2.26 y anteriores podría provocar que estas funciones devuelvan un puntero a un área de la memoria dinámica (heap) demasiado pequeña, pudiendo corromper el heap. • http://bugs.debian.org/878159 http://www.securityfocus.com/bid/102912 https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2018:3092 https://security.netapp.com/advisory/ntap-20190404-0003 https://sourceware.org/bugzilla/show_bug.cgi?id=22343 https://usn.ubuntu.com/4218-1 https://usn.ubuntu.com/4416-1 https://www.oracle.com/technetwork/security-advisory/cpuapr2019-5072813.html https://access.redhat.com/security/cve/CVE-2018-6485 https:/ • CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •
