CVE-2011-0521 – kernel: av7110 negative array offset
https://notcve.org/view.php?id=CVE-2011-0521
The dvb_ca_ioctl function in drivers/media/dvb/ttpci/av7110_ca.c in the Linux kernel before 2.6.38-rc2 does not check the sign of a certain integer field, which allows local users to cause a denial of service (memory corruption) or possibly have unspecified other impact via a negative value. La función dvb_ca_ioctl function en drivers/media/dvb/ttpci/av7110_ca.c para el kernel Linux anterior a v2.6.38-rc2 no comprueba el signo de un campo entero determinado, lo que permite a usuarios locales causar una denegación de servicio (corrupción de memoria) o posiblemente tener un impacto no especificado a través de un valor negativo. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=cb26a24ee9706473f31d34cc259f4dcf45cd0644 http://openwall.com/lists/oss-security/2011/01/24/2 http://openwall.com/lists/oss-security/2011/01/25/2 http://secunia.com/advisories/43009 http://secunia.com/advisories/46397 http://www.kernel.org/pub/linux/kernel/v2.6/testing/ChangeLog-2.6.38-rc2 http://www.securityfocus.com/archive/1/520102/100/0/threaded http://www.securityfocus.com/bid/45986 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2010-4656 – kernel: iowarrior usb device heap overflow
https://notcve.org/view.php?id=CVE-2010-4656
The iowarrior_write function in drivers/usb/misc/iowarrior.c in the Linux kernel before 2.6.37 does not properly allocate memory, which might allow local users to trigger a heap-based buffer overflow, and consequently cause a denial of service or gain privileges, via a long report. La función iowarrior_write en drivers/usb/misc/iowarrior.c en el kernel Linux anterior a v2.6.37 no asigna memoria adecuadamente, lo que permite a usuarios locales desencadenar un desbordamiento de búfer basado en memoria dinámica, y en consecuencia provocar una denegación de servicio o obtener privilegios a través de un informe largo. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=3ed780117dbe5acb64280d218f0347f238dafed0 http://openwall.com/lists/oss-security/2011/01/24/9 http://openwall.com/lists/oss-security/2011/01/25/3 http://openwall.com/lists/oss-security/2011/01/25/4 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.37 http://www.securityfocus.com/bid/46069 http://www.ubuntu.com/usn/USN-1146-1 https://bugzilla.redhat.com/show_bug.cgi?id • CWE-787: Out-of-bounds Write •
CVE-2010-4649 – kernel: IB/uverbs: Handle large number of entries in poll CQ
https://notcve.org/view.php?id=CVE-2010-4649
Integer overflow in the ib_uverbs_poll_cq function in drivers/infiniband/core/uverbs_cmd.c in the Linux kernel before 2.6.37 allows local users to cause a denial of service (memory corruption) or possibly have unspecified other impact via a large value of a certain structure member. Desbordamiento de enteros en la función ib_uverbs_poll_cq en drivers/InfiniBand/core/uverbs_cmd.c en el kernel de Linux antes de v2.6.37 permite a usuarios locales causar una denegación de servicio (corrupción de memoria) o posiblemente tener un impacto no especificado a través de un valor grande de un determinado miembro de una estructura. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=7182afea8d1afd432a17c18162cc3fd441d0da93 http://rhn.redhat.com/errata/RHSA-2011-0927.html http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.37 http://www.securityfocus.com/bid/46073 https://bugzilla.redhat.com/show_bug.cgi?id=667916 https://access.redhat.com/security/cve/CVE-2010-4649 • CWE-190: Integer Overflow or Wraparound •
CVE-2010-4256

La función pipe_fcntl en fs/pipe.c en el kernel de Linux anteriores a v2.6.37 no determinar correctamente si un archivo es una tubería (pipe) con nombre, que permite a usuarios locales causar una denegación de servicio a través de una llamada F_SETPIPE_SZ fcntl. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=c66fb347946ebdd5b10908866ecc9fa05ee2cf3d http://openwall.com/lists/oss-security/2010/11/30/6 http://openwall.com/lists/oss-security/2010/11/30/9 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.37 • CWE-20: Improper Input Validation •
CVE-2010-4243 – Linux Kernel 2.6.37 - 'setup_arg_pages()' Denial of Service
https://notcve.org/view.php?id=CVE-2010-4243
fs/exec.c in the Linux kernel before 2.6.37 does not enable the OOM Killer to assess use of stack memory by arrays representing the (1) arguments and (2) environment, which allows local users to cause a denial of service (memory consumption) via a crafted exec system call, aka an "OOM dodging issue," a related issue to CVE-2010-3858. fs/exec.c del kernel de Linux en versiones anteriores a la 2.6.37 no habilita el "OOM Killer" para evaluar el uso de la memoria de pila por los arrays de los (1) argumentos y (2) entorno, lo que permite a usuarios locales provocar una denegación de servicio (consumo de la memoria) a través de una llamada del sistema exec modificada. También conocido como "OOM dodging issue".
