CVE-2011-4517 – jasper: heap buffer overflow flaws lead to arbitrary code execution (CERT VU#887409)
https://notcve.org/view.php?id=CVE-2011-4517
The jpc_crg_getparms function in libjasper/jpc/jpc_cs.c in JasPer 1.900.1 uses an incorrect data type during a certain size calculation, which allows remote attackers to trigger a heap-based buffer overflow and execute arbitrary code, or cause a denial of service (heap memory corruption), via a crafted component registration (CRG) marker segment in a JPEG2000 file. La función jpc_crg_getparms de libjasper/jpc/jpc_cs.c de JasPer 1.900.1 utiliza un tipo de datos incorrecto durante un cálculo determinado de tamaño, lo que permite a atacantes remotos provocar un desbordamiento de buffer de memoria dinámica y ejecutar código arbitrario, o provocar una denegación de servicio (corrupción de memoria dinámica), a través de un archivo JPEG2000 mal formado. A heap-based buffer overflow flaw was found in the way JasPer decoded JPEG 2000 compressed image files. An attacker could create a malicious JPEG 2000 compressed image file that, when opened, would cause applications that use JasPer (such as Nautilus) to crash or, potentially, execute arbitrary code. • http://lists.fedoraproject.org/pipermail/package-announce/2011-December/071458.html http://lists.fedoraproject.org/pipermail/package-announce/2012-January/071561.html http://lists.opensuse.org/opensuse-security-announce/2011-12/msg00010.html http://osvdb.org/77596 http://rhn.redhat.com/errata/RHSA-2015-0698.html http://secunia.com/advisories/47193 http://secunia.com/advisories/47306 http://secunia.com/advisories/47353 http://www-01.ibm.com/support/docview.wss?uid=swg21660640 http://www • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

Heap-based buffer overflow in the jpc_cox_getcompparms function in libjasper/jpc/jpc_cs.c in JasPer 1.900.1 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted numrlvls value in a coding style default (COD) marker segment in a JPEG2000 file. Desbordamiento de buffer de memoria dinámica en la función jpc_cox_getcompparms de libjasper/jpc/jpc_cs.c de JasPer 1.900.1 permite a atacantes remotos ejecutar código arbitrario o provocar una denegación de servicio (corrupción de memoria) a través de un valor numrlvls de un archivo JPEG2000.

CVE-2011-1526 – krb5-appl: ftpd incorrect group privilege dropping (MITKRB5-SA-2011-005)
https://notcve.org/view.php?id=CVE-2011-1526
ftpd.c in the GSS-API FTP daemon in MIT Kerberos Version 5 Applications (aka krb5-appl) 1.0.1 and earlier does not check the krb5_setegid return value, which allows remote authenticated users to bypass intended group access restrictions, and create, overwrite, delete, or read files, via standard FTP commands, related to missing autoconf tests in a configure script. ftpd.c en el demonio GSS-API FTP en MIT Kerberos Version 5 Applications (también conocido como krb5-appl) v1.0.1 y anteriores no comprueban el valor de retorno krb5_setegid, lo que permite que usuarios autenticados de forma remota evitar las restricciones de acceso de grupo, y crear, sobreescribir, borrar, o leer ficheros, a través de comandos FTP estándar, relacionado con test autoconfigurados olvidados en un script configurado. It was found that ftpd, a Kerberos-aware FTP server, did not properly drop privileges. On Red Hat Enterprise Linux 5, the ftpd daemon did not check for the potential failure of the krb5_setegid() function call. On systems where the set real, set effective, or set saved group ID system calls might fail, a remote FTP user could use this flaw to gain unauthorized read or write access to files that were owned by the root group. • http://lists.fedoraproject.org/pipermail/package-announce/2011-July/062681.html http://lists.fedoraproject.org/pipermail/package-announce/2011-July/062699.html http://lists.opensuse.org/opensuse-security-announce/2011-10/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2012-01/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2012-01/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2012-01/msg00005.html http://lists.opensuse.org/opensuse-security-announce/201 • CWE-269: Improper Privilege Management •
CVE-2011-0762 – vsftpd 2.3.2 - Denial of Service
https://notcve.org/view.php?id=CVE-2011-0762
The vsf_filename_passes_filter function in ls.c in vsftpd before 2.3.3 allows remote authenticated users to cause a denial of service (CPU consumption and process slot exhaustion) via crafted glob expressions in STAT commands in multiple FTP sessions, a different vulnerability than CVE-2010-2632. La función vsf_filename_passes_filter de ls.c de vsftpd en versiones anteriores a la 2.3.3 permite a usuarios autenticados remotos provocar una denegación de servicio (consumo de toda la CPU y agotamiento de los slots de procesos) a través de una expresión glob modificada en comandos STAT en múltiples sesiones FTP. Una vulnerabilidad distinta a la CVE-2010-2632. Vsftpd versions 2.3.2 on NetBSD and 2.3.0 on Ubuntu suffer from a remote denial of service vulnerability. • https://www.exploit-db.com/exploits/16270 ftp://vsftpd.beasts.org/users/cevans/untar/vsftpd-2.3.4/Changelog http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=622741 http://cxib.net/stuff/vspoc232.c http://jvn.jp/en/jp/JVN37417423/index.html http://lists.fedoraproject.org/pipermail/package-announce/2011-March/055881.html http://lists.fedoraproject.org/pipermail/package-announce/2011-March/055882.html http://lists.fedoraproject.org/pipermail/package-announce/2011-March/055957.html http • CWE-400: Uncontrolled Resource Consumption •
