Multiple integer overflows in ber-decoder.c in Libksba before 1.3.3 allow remote attackers to cause a denial of service (crash) via crafted BER data, which leads to a buffer overflow. Múltiples desbordamientos de enteros en ber-decoder.c en Libksba en versiones anteriores a 1.3.3 permiten a atacantes remotos provocar una caída del servicio (caída) a través de una información BER manipulada, lo que conduce a un desbordamiento del buffer. • http://git.gnupg.org/cgi-bin/gitweb.cgi?p=libksba.git%3Ba=commit%3Bh=aea7b6032865740478ca4b706850a5217f1c3887 http://www.openwall.com/lists/oss-security/2016/04/29/5 http://www.openwall.com/lists/oss-security/2016/04/29/8 http://www.ubuntu.com/usn/USN-2982-1 https://security.gentoo.org/glsa/201604-04 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

Off-by-one error in the append_utf8_value function in the DN decoder (dn.c) in Libksba before 1.3.4 allows remote attackers to cause a denial of service (out-of-bounds read) via invalid utf-8 encoded data. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-4356. El error off-by-one en la función append_utf8_value en el decodificador DN (dn.c) en Libksba en versiones anteriores a 1.3.4 permite a atacantes remotos provocar una caída de servicio (lectura fuera de rango) a través de una codificación de la información utf-8. NOTA: esta vulnerabilidad existe debido a una reparación incompleta de CVE-2016-4356. • http://git.gnupg.org/cgi-bin/gitweb.cgi?p=libksba.git%3Ba=commit%3Bh=6be61daac047d8e6aa941eb103f8e71a1d4e3c75 http://lists.opensuse.org/opensuse-updates/2016-05/msg00087.html http://lists.opensuse.org/opensuse-updates/2016-06/msg00028.html http://www.openwall.com/lists/oss-security/2016/05/10/3 http://www.openwall.com/lists/oss-security/2016/05/10/4 http://www.ubuntu.com/usn/USN-2982-1 • CWE-189: Numeric Errors •

The append_utf8_value function in the DN decoder (dn.c) in Libksba before 1.3.3 allows remote attackers to cause a denial of service (out-of-bounds read) by clearing the high bit of the byte after invalid utf-8 encoded data. La función append_utf8_value en el decodificador DN (dn.c) en Libksba en versiones anteriores a 1.3.3 permite a atacantes remotos provocar una caída de servicio (lectura fuera de rango) borrando el bit del byte después de datos codificados UTF-8 no válidos. • http://git.gnupg.org/cgi-bin/gitweb.cgi?p=libksba.git%3Ba=commit%3Bh=243d12fdec66a4360fbb3e307a046b39b5b4ffc3 http://www.openwall.com/lists/oss-security/2016/04/29/5 http://www.openwall.com/lists/oss-security/2016/04/29/8 http://www.openwall.com/lists/oss-security/2016/05/10/3 http://www.ubuntu.com/usn/USN-2982-1 https://security.gentoo.org/glsa/201604-04 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
