CVE-2014-5045 – kernel: vfs: refcount issues during unmount on symlink
https://notcve.org/view.php?id=CVE-2014-5045
The mountpoint_last function in fs/namei.c in the Linux kernel before 3.15.8 does not properly maintain a certain reference count during attempts to use the umount system call in conjunction with a symlink, which allows local users to cause a denial of service (memory consumption or use-after-free) or possibly have unspecified other impact via the umount program. La función mountpoint_last en fs/namei.c en el kernel de Linux anterior a 3.15.8 no mantiene debidamente cierta cuenta de referencias durante intentos de utilizar la llamada al sistema umount en conjunto con un enlace simbólico, lo que permite a usuarios locales causar una denegación de servicio (consumo de memoria o uso después de liberación) o posiblemente tener otro impacto no especificado a través del programa umount. A flaw was found in the way the Linux kernel's VFS subsystem handled reference counting when performing unmount operations on symbolic links. A local, unprivileged user could use this flaw to exhaust all available memory on the system or, potentially, trigger a use-after-free error, resulting in a system crash or privilege escalation. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=295dc39d941dc2ae53d5c170365af4c9d5c16212 http://rhn.redhat.com/errata/RHSA-2015-0062.html http://secunia.com/advisories/60353 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.15.8 http://www.openwall.com/lists/oss-security/2014/07/24/2 http://www.securityfocus.com/bid/68862 https://bugzilla.redhat.com/show_bug.cgi?id=1122472 https://github.com/torvalds/linux/commit/295dc39d941dc2ae53d5c170365af4 • CWE-59: Improper Link Resolution Before File Access ('Link Following') •
CVE-2014-2483 – OpenJDK: Restrict use of privileged annotations (Libraries, 8034985)
https://notcve.org/view.php?id=CVE-2014-2483
Unspecified vulnerability in the Java SE component in Oracle Java SE Java SE 7u60 and OpenJDK 7 allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to Libraries, a different vulnerability than CVE-2014-4223. NOTE: the previous information is from the July 2014 CPU. Oracle has not commented on another vendor's claim that the issue is related to improper restriction of the "use of privileged annotations." Vulnerabilidad no especificada en el componente Java SE en Oracle Java SE Java SE 7u60 y OpenJDK 7 permite a atacantes remotos afectar la confidencialidad, integridad y disponibilidad a través de vectores relacionados con Libraries, una vulnerabilidad diferente a CVE-2014-4223.

CVE-2014-4650 – Python CGIHTTPServer - Encoded Directory Traversal
https://notcve.org/view.php?id=CVE-2014-4650
The CGIHTTPServer module in Python 2.7.5 and 3.3.4 does not properly handle URLs in which URL encoding is used for path separators, which allows remote attackers to read script source code or conduct directory traversal attacks and execute unintended code via a crafted character sequence, as demonstrated by a %2f separator. El módulo CGIHTTPServer en Python versiones 2.7.5 y 3.3.4, no maneja apropiadamente las URL en las que la codificación de URL es usada para los separadores de ruta, lo que permite a atacantes remotos leer el código fuente del script o conducir un salto de directorio y ejecutar código no deseado por medio de una secuencia de caracteres diseñada, como es demostrado mediante un separador %2f. It was discovered that the CGIHTTPServer module incorrectly handled URL encoded paths. A remote attacker could use this flaw to execute scripts outside of the cgi-bin directory, or disclose source of scripts in the cgi-bin directory. • https://www.exploit-db.com/exploits/33894 http://bugs.python.org/issue21766 http://openwall.com/lists/oss-security/2014/06/26/3 https://access.redhat.com/security/cve/cve-2014-4650 https://access.redhat.com/security/cve/CVE-2014-4650 https://bugzilla.redhat.com/show_bug.cgi?id=1113527 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-138: Improper Neutralization of Special Elements •
