CVE-2015-2808 – SSL/TLS: "Invariance Weakness" vulnerability in RC4 stream cipher
https://notcve.org/view.php?id=CVE-2015-2808
The RC4 algorithm, as used in the TLS protocol and SSL protocol, does not properly combine state data with key data during the initialization phase, which makes it easier for remote attackers to conduct plaintext-recovery attacks against the initial bytes of a stream by sniffing network traffic that occasionally relies on keys affected by the Invariance Weakness, and then using a brute-force approach involving LSB values, aka the "Bar Mitzvah" issue. El algoritmo RC4, utilizado en el protocolo TLS y el protocolo SSL, no combina correctamente los datos de estados con los datos de claves durante la fase de inicialización, lo que facilita a atacantes remotos realizar ataques de recuperación de texto claro contra los bytes iniciales de un flujo mediante la captura de trafico de la red que ocasionalmente depende de claves afectadas por la debilidad de la invariabilidad (Invariance Weakness), y posteriormente utilizar un acercamiento de fuerza bruta que involucra valores LSB, también conocido como el problema de 'Bar Mitzvah'. • http://h20564.www2.hpe.com/hpsc/doc/public/display?docId=emr_na-c04779034 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10705 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10727 http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00013.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00014.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00015.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00022.html • CWE-327: Use of a Broken or Risky Cryptographic Algorithm •
CVE-2014-8130 – libtiff: divide by zero in the tiffdither tool
https://notcve.org/view.php?id=CVE-2014-8130
The _TIFFmalloc function in tif_unix.c in LibTIFF 4.0.3 does not reject a zero size, which allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted TIFF image that is mishandled by the TIFFWriteScanline function in tif_write.c, as demonstrated by tiffdither. La función _TIFFmalloc en tif_unix.c en LibTIFF 4.0.3 no rechaza un tamaño cero, lo que permite que atacantes remotos provoquen una denegación de servicio (error de división entre cero y cierre inesperado de la aplicación) mediante una imagen TIFF manipulada que es gestionada incorrectamente por la función TIFFWriteScanline en tif_write.c, tal y como demuestra tiffdither. • http://bugzilla.maptools.org/show_bug.cgi?id=2483 http://lists.apple.com/archives/security-announce/2015/Jun/msg00001.html http://lists.apple.com/archives/security-announce/2015/Jun/msg00002.html http://openwall.com/lists/oss-security/2015/01/24/15 http://rhn.redhat.com/errata/RHSA-2016-1546.html http://rhn.redhat.com/errata/RHSA-2016-1547.html http://support.apple.com/kb/HT204941 http://support.apple.com/kb/HT204942 http://www.conostix.com/pub/adv/CVE-2014-8130 • CWE-369: Divide By Zero •
CVE-2014-8129 – libtiff: out-of-bounds read/write with malformed TIFF image in tiff2pdf
https://notcve.org/view.php?id=CVE-2014-8129
LibTIFF 4.0.3 allows remote attackers to cause a denial of service (out-of-bounds write) or possibly have unspecified other impact via a crafted TIFF image, as demonstrated by failure of tif_next.c to verify that the BitsPerSample value is 2, and the t2p_sample_lab_signed_to_unsigned function in tiff2pdf.c. LibTIFF 4.0.3 permite que atacantes remotos provoquen una denegación de servicio (escritura fuera de límites) u otro tipo de impacto sin especificar mediante una imagen TIFF manipulada. Esto se demuestra por el fracaso de tif_next.c a la hora de verificar que el valor de BitsPerSample es 2 y la función t2p_sample_lab_signed_to_unsigned en tiff2pdf.c. • http://bugzilla.maptools.org/show_bug.cgi?id=2487 http://bugzilla.maptools.org/show_bug.cgi?id=2488 http://lists.apple.com/archives/security-announce/2015/Jun/msg00001.html http://lists.apple.com/archives/security-announce/2015/Jun/msg00002.html http://openwall.com/lists/oss-security/2015/01/24/15 http://rhn.redhat.com/errata/RHSA-2016-1546.html http://rhn.redhat.com/errata/RHSA-2016-1547.html http://support.apple.com/kb/HT204941 http://support.apple.com/kb/HT2049 • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •
CVE-2014-8160 – kernel: iptables restriction bypass if a protocol handler kernel module not loaded
https://notcve.org/view.php?id=CVE-2014-8160
net/netfilter/nf_conntrack_proto_generic.c in the Linux kernel before 3.18 generates incorrect conntrack entries during handling of certain iptables rule sets for the SCTP, DCCP, GRE, and UDP-Lite protocols, which allows remote attackers to bypass intended access restrictions via packets with disallowed port numbers. net/netfilter/nf_conntrack_proto_generic.c en el kernel de Linux anterior a 3.18 genera entradas conntrack incorrectas durante el manejo de ciertos juegos de reglas iptables para los protocolos SCTP, DCCP, GRE, y UDP-Lite, lo que permite a atacantes remotos evadir las restricciones de acceso a través de paquetes con números de puertos rechazados. A flaw was found in the way the Linux kernel's netfilter subsystem handled generic protocol tracking. As demonstrated in the Stream Control Transmission Protocol (SCTP) case, a remote attacker could use this flaw to bypass intended iptables rule restrictions when the associated connection tracking module was not loaded on the system. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=db29a9508a9246e77087c5531e45b2c88ec6988b http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00015.html http://rhn.redhat.com/errata/RHSA-2015-0284.html http://rhn.redhat.com/errata/RHSA • CWE-20: Improper Input Validation •
