CVE-2015-3195 – OpenSSL: X509_ATTRIBUTE memory leak
https://notcve.org/view.php?id=CVE-2015-3195
The ASN1_TFLG_COMBINE implementation in crypto/asn1/tasn_dec.c in OpenSSL before 0.9.8zh, 1.0.0 before 1.0.0t, 1.0.1 before 1.0.1q, and 1.0.2 before 1.0.2e mishandles errors caused by malformed X509_ATTRIBUTE data, which allows remote attackers to obtain sensitive information from process memory by triggering a decoding failure in a PKCS#7 or CMS application. La implementación ASN1_TFLG_COMBINE en crypto/asn1/tasn_dec.c en OpenSSL en versiones anteriores a 0.9.8zh, 1.0.0 en versiones anteriores a 1.0.0t, 1.0.1 en versiones anteriores a 1.0.1q y 1.0.2 en versiones anteriores a 1.0.2e no maneja correctamente los errores provocados por datos X509_ATTRIBUTE malformados, lo que permite a atacantes remotos obtener información sensible de memoria de proceso desencadenando un fallo de decodificación en una aplicación PKCS#7 o CMS. A memory leak vulnerability was found in the way OpenSSL parsed PKCS#7 and CMS data. A remote attacker could use this flaw to cause an application that parses PKCS#7 or CMS data from untrusted sources to use an excessive amount of memory and possibly crash. • http://fortiguard.com/advisory/openssl-advisory-december-2015 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10733 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10761 http://lists.apple.com/archives/security-announce/2016/Mar/msg00004.html http://lists.fedoraproject.org/pipermail/package-announce/2015-December/173801.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00009.html http://lists.opensuse& • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-401: Missing Release of Memory after Effective Lifetime •
CVE-2015-8391 – pcre: inefficient posix character class syntax check (8.38/16)
https://notcve.org/view.php?id=CVE-2015-8391
The pcre_compile function in pcre_compile.c in PCRE before 8.38 mishandles certain [: nesting, which allows remote attackers to cause a denial of service (CPU consumption) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror. La función pcre_compile en pcre_compile.c en PCRE en versiones anteriores a 8.38 no maneja correctamente cierta anidación [: , lo que permite a atacantes remotos causar una denegación de servicio (consumo de CPU) o posiblemente tener otro impacto no especificado a través de una expresión regular manipulada, según lo demostrado por un objeto JavaScript RegExp encontrado por Konqueror. • http://lists.fedoraproject.org/pipermail/package-announce/2016-January/174931.html http://rhn.redhat.com/errata/RHSA-2016-1025.html http://rhn.redhat.com/errata/RHSA-2016-2750.html http://vcs.pcre.org/pcre/code/trunk/ChangeLog?view=markup http://www-01.ibm.com/support/docview.wss?uid=isg3T1023886 http://www.openwall.com/lists/oss-security/2015/11/29/1 http://www.oracle.com/technetwork/topics/security/linuxbulletinapr2016-2952096.html http://www.securityfocus.com/bid/82990 https: • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-407: Inefficient Algorithmic Complexity •
CVE-2015-5006 – JDK: local disclosure of kerberos credentials cache
https://notcve.org/view.php?id=CVE-2015-5006
IBM Java Security Components in IBM SDK, Java Technology Edition 8 before SR2, 7 R1 before SR3 FP20, 7 before SR9 FP20, 6 R1 before SR8 FP15, and 6 before SR16 FP15 allow physically proximate attackers to obtain sensitive information by reading the Kerberos Credential Cache. IBM Java Security Components en IBM SDK, Java Technology Edition 8 en versiones anteriores a SR2, 7 R1 en versiones anteriores a SR3 FP20, 7 en versiones anteriores a SR9 FP20, 6 R1 en versiones anteriores a SR8 FP15 y 6 en versiones anteriores a SR16 FP15 permite a atacantes físicamente próximos obtener información sensible mediante la lectura del Kerberos Credential Cache. • http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00014.html http://lists.opensuse.org/opensuse-security-announce/2016-01 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2015-3276 – openldap: incorrect multi-keyword mode cipherstring parsing
https://notcve.org/view.php?id=CVE-2015-3276
The nss_parse_ciphers function in libraries/libldap/tls_m.c in OpenLDAP does not properly parse OpenSSL-style multi-keyword mode cipher strings, which might cause a weaker than intended cipher to be used and allow remote attackers to have unspecified impact via unknown vectors. La función nss_parse_ciphers en libraries/libldap/tls_m.c en OpenLDAP no analiza adecuadamente cadenas de cifrado en modo multiclave de estilo OpenSSL, lo que podría provocar el uso de un cifrado más débil que el previsto y permitir a atacantes remotos tener un impacto no especificado a través de vectores desconocidos. A flaw was found in the way OpenLDAP parsed OpenSSL-style cipher strings. As a result, OpenLDAP could potentially use ciphers that were not intended to be enabled. • http://rhn.redhat.com/errata/RHSA-2015-2131.html http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2015-2719645.html http://www.securitytracker.com/id/1034221 https://bugzilla.redhat.com/show_bug.cgi?id=1238322 https://access.redhat.com/security/cve/CVE-2015-3276 • CWE-682: Incorrect Calculation •
CVE-2015-7837 – kernel: securelevel disabled after kexec
https://notcve.org/view.php?id=CVE-2015-7837
The Linux kernel, as used in Red Hat Enterprise Linux 7, kernel-rt, and Enterprise MRG 2 and when booted with UEFI Secure Boot enabled, allows local users to bypass intended securelevel/secureboot restrictions by leveraging improper handling of secure_boot flag across kexec reboot. El kernel de Linux, tal y como se emplea en Red Hat Enterprise Linux 7, kernel-rt y Enterprise MRG 2 y cuando se emplea con UEFI Secure Boot habilitado, permite que usuarios locales omitan las restricciones securelevel/secureboot previstas aprovechando la gestión incorrecta de la marca secure_boot cuando se reinicia kexec. A flaw was found in the way the Linux kernel handled the securelevel functionality after performing a kexec operation. A local attacker could use this flaw to bypass the security mechanism of the securelevel/secureboot combination. • http://rhn.redhat.com/errata/RHSA-2015-2152.html http://rhn.redhat.com/errata/RHSA-2015-2411.html http://www.openwall.com/lists/oss-security/2015/10/15/6 http://www.securityfocus.com/bid/77097 https://bugzilla.redhat.com/show_bug.cgi?id=1272472 https://github.com/mjg59/linux/commit/4b2b64d5a6ebc84214755ebccd599baef7c1b798 https://access.redhat.com/security/cve/CVE-2015-7837 • CWE-254: 7PK - Security Features CWE-456: Missing Initialization of a Variable •
