CVSS: 7.5EPSS: 1%CPEs: 7EXPL: 0CVE-2014-6051 – libvncserver: integer overflow flaw, leading to a heap-based buffer overflow in screen size handling
https://notcve.org/view.php?id=CVE-2014-6051
Integer overflow in the MallocFrameBuffer function in vncviewer.c in LibVNCServer 0.9.9 and earlier allows remote VNC servers to cause a denial of service (crash) and possibly execute arbitrary code via an advertisement for a large screen size, which triggers a heap-based buffer overflow. Desbordamiento de enteros en la función MallocFrameBuffer en vncviewer.c en LibVNCServer 0.9.9 y anteriores permite a servidores remotos VNC causar una denegación de servicio (caída) y posiblemente ejecutar código arbitrario a través de un anuncio para un tamaño grande de pantalla, lo que provoca un desbordamiento de buffer basado en memoria dinámica. An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way screen sizes were handled by LibVNCServer. A malicious VNC server could use this flaw to cause a client to crash or, potentially, execute arbitrary code in the client. • http://lists.fedoraproject.org/pipermail/package-announce/2014-October/139654.html http://lists.fedoraproject.org/pipermail/package-announce/2014-September/139445.html http://lists.opensuse.org/opensuse-updates/2015-12/msg00022.html http://rhn.redhat.com/errata/RHSA-2015-0113.html http://seclists.org/oss-sec/2014/q3/639 http://secunia.com/advisories/61506 http://www.debian.org/security/2014/dsa-3081 http://www.ocert.org/advisories/ocert-2014-007.html http://www.openwall.com/lists& • CWE-122: Heap-based Buffer Overflow CWE-189: Numeric Errors •

https://notcve.org/view.php?id=CVE-2014-6055
Multiple stack-based buffer overflows in the File Transfer feature in rfbserver.c in LibVNCServer 0.9.9 and earlier allow remote authenticated users to cause a denial of service (crash) and possibly execute arbitrary code via a (1) long file or (2) directory name or the (3) FileTime attribute in a rfbFileTransferOffer message. Múltiples desbordamientos de buffer basado en pila en la caracteristica File Transfer en rfbserver.c en LibVNCServer 0.9.9 y anteriores permiten a usuarios remotos autenticados causar una denegación de servicio (caída) y posiblemente ejecutar código arbitrario a través de un (1) fichero largo o (2) nombre de directorio o el (3) atributo FileTime en un mensaje rfbFileTransferOffer. Two stack-based buffer overflow flaws were found in the way LibVNCServer handled file transfers. A remote attacker could use this flaw to crash the VNC server using a malicious VNC client. • http://lists.fedoraproject.org/pipermail/package-announce/2014-October/139654.html http://lists.fedoraproject.org/pipermail/package-announce/2014-September/139445.html http://lists.opensuse.org/opensuse-updates/2015-12/msg00022.html http://rhn.redhat.com/errata/RHSA-2015-0113.html http://seclists.org/oss-sec/2014/q3/639 http://secunia.com/advisories/61506 http://www.debian.org/security/2014/dsa-3081 http://www.ocert.org/advisories/ocert-2014-007.html http://www.openwall.com/lists& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-121: Stack-based Buffer Overflow •

https://notcve.org/view.php?id=CVE-2014-7169
GNU Bash through 4.3 bash43-025 processes trailing strings after certain malformed function definitions in the values of environment variables, which allows remote attackers to write to files or possibly have unknown other impact via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-6271. GNU Bash hasta 4.3 bash43-025 procesa cadenas finales después de la definición malformada de funciones en los valores de variables de entorno, lo que permite a atacantes remotos escribir hacia ficheros o posiblemente tener otro impacto desconocido a través de un entorno manipulado, tal y como se ha demostrado por vectores que involucran la característica ForceCommand en sshd OpenSSH, los módulos mod_cgi y mod_cgid en el Apache HTTP Server, scripts ejecutados por clientes DHCP no especificados, y otras situaciones en la cual establecer el entorno ocurre a través de un límite privilegiado de la ejecución de Bash. Nota: Esta vulnerabilidad existe debido a una solución incompleta para CVE-2014-6271. It was found that the fix for CVE-2014-6271 was incomplete, and Bash still allowed certain characters to be injected into other environments via specially crafted environment variables. • https://www.exploit-db.com/exploits/34777 https://www.exploit-db.com/exploits/34895 https://www.exploit-db.com/exploits/34839 https://www.exploit-db.com/exploits/36503 https://www.exploit-db.com/exploits/36504 https://www.exploit-db.com/exploits/34766 https://www.exploit-db.com/exploits/35115 https://www.exploit-db.com/exploits/36933 https://www.exploit-db.com/exploits/34765 https://www.exploit-db.com/exploits/34860 https://www.exploit-db.com/exploits/34879 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-228: Improper Handling of Syntactically Invalid Structure •

CVSS: 6.2EPSS: 0%CPEs: 4EXPL: 1CVE-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') •
