https://notcve.org/view.php?id=CVE-2009-2698
The udp_sendmsg function in the UDP implementation in (1) net/ipv4/udp.c and (2) net/ipv6/udp.c in the Linux kernel before 2.6.19 allows local users to gain privileges or cause a denial of service (NULL pointer dereference and system crash) via vectors involving the MSG_MORE flag and a UDP socket. La función udp_sendmsg en la implementación UDP en los archivos (1) net/ipv4/udp.c y (2) net/ipv6/udp.c en el kernel de Linux anterior a versión 2.6.19, permite a los usuarios locales obtener privilegios o causar una denegación de servicio (Desreferencia de puntero NULL y bloqueo de sistema) por medio de vectores que involucran el flag MSG_MORE y un socket UDP. • https://www.exploit-db.com/exploits/9575 https://www.exploit-db.com/exploits/9574 https://www.exploit-db.com/exploits/9542 https://github.com/xiaoxiaoleo/CVE-2009-2698 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=1e0c14f49d6b393179f423abbac47f85618d3d46 http://lists.opensuse.org/opensuse-security-announce/2009-08/msg00008.html http://rhn.redhat.com/errata/RHSA-2009-1222.html http://rhn.redhat.com/errata/RHSA-2009-1223.html http://secunia.com&# • CWE-476: NULL Pointer Dereference •
CVSS: 7.2EPSS: 0%CPEs: 27EXPL: 2CVE-2009-2848 – kernel: execve: must clear current->clear_child_tid
https://notcve.org/view.php?id=CVE-2009-2848
The execve function in the Linux kernel, possibly 2.6.30-rc6 and earlier, does not properly clear the current->clear_child_tid pointer, which allows local users to cause a denial of service (memory corruption) or possibly gain privileges via a clone system call with CLONE_CHILD_SETTID or CLONE_CHILD_CLEARTID enabled, which is not properly handled during thread creation and exit. Una función execve en el kernel de Linux, posiblemente versión 2.6.30-rc6 y anteriores, no borra apropiadamente el puntero de current-)clear_child_tid, lo que permite a los usuarios locales causar una denegación de servicio (corrupción de memoria) o posiblemente alcanzar privilegios por medio de un sistema de clonación que llama con CLONE_CHILD_SETTID o CLONE_CHILD_CLEARTID habilitadas, que no son manejados apropiadamente durante la creación y salida de hilos (subprocesos). • http://article.gmane.org/gmane.linux.kernel/871942 http://lists.opensuse.org/opensuse-security-announce/2009-11/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2009-11/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2010-02/msg00005.html http://rhn.redhat.com/errata/RHSA-2009-1243.html http://secunia.com/advisories/35983 http://secunia.com/advisories/36501 http://secunia.com/advisories/36562 http://secunia.com/advisories/36759 http://secunia.com • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-269: Improper Privilege Management •
CVSS: 7.8EPSS: 0%CPEs: 13EXPL: 14CVE-2009-2692 – Linux Kernel 2.x (Android) - 'sock_sendpage()' Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2009-2692
The Linux kernel 2.6.0 through 2.6.30.4, and 2.4.4 through 2.4.37.4, does not initialize all function pointers for socket operations in proto_ops structures, which allows local users to trigger a NULL pointer dereference and gain privileges by using mmap to map page zero, placing arbitrary code on this page, and then invoking an unavailable operation, as demonstrated by the sendpage operation (sock_sendpage function) on a PF_PPPOX socket. El kernel de Linux versiones 2.6.0 hasta 2.6.30.4 y 2.4.4 hasta 2.4.37.4, no inicia todos los punteros de función para operaciones de socket en estructuras de proto_ops, lo que permite a los usuarios locales activar una desreferencia de puntero NULL y alcanzar privilegios mediante el uso de mmap que asigna la página cero, inserta el código arbitrario en esta página y luego invoca una operación no disponible, como es demostrado por la operación de sendpage (función sock_sendpage) en un socket PF_PPPOX. • https://www.exploit-db.com/exploits/9477 https://www.exploit-db.com/exploits/19933 https://www.exploit-db.com/exploits/9545 https://www.exploit-db.com/exploits/9598 https://www.exploit-db.com/exploits/9479 https://www.exploit-db.com/exploits/9641 https://www.exploit-db.com/exploits/9435 https://www.exploit-db.com/exploits/9436 https://github.com/jdvalentini/CVE-2009-2692 http://archives.neohapsis.com/archives/fulldisclosure/2009-08/0174.html http://blog.cr0.or • CWE-476: NULL Pointer Dereference CWE-908: Use of Uninitialized Resource •

https://notcve.org/view.php?id=CVE-2009-1891
The mod_deflate module in Apache httpd 2.2.11 and earlier compresses large files until completion even after the associated network connection is closed, which allows remote attackers to cause a denial of service (CPU consumption).

The stream_reqbody_cl function in mod_proxy_http.c in the mod_proxy module in the Apache HTTP Server before 2.3.3, when a reverse proxy is configured, does not properly handle an amount of streamed data that exceeds the Content-Length value, which allows remote attackers to cause a denial of service (CPU consumption) via crafted requests.
