CVE-2012-2372 – kernel: rds-ping cause kernel panic
https://notcve.org/view.php?id=CVE-2012-2372
The rds_ib_xmit function in net/rds/ib_send.c in the Reliable Datagram Sockets (RDS) protocol implementation in the Linux kernel 3.7.4 and earlier allows local users to cause a denial of service (BUG_ON and kernel panic) by establishing an RDS connection with the source IP address equal to the IPoIB interface's own IP address, as demonstrated by rds-ping. La función rds_ib_xmit en net/rds/ib_send.c en la implementación fiable de datagramas de protocolo Sockets (RDS) en el kernel Linux v3.7.4 y anteriores permite a usuarios locales provocar una denegación de servicio (BUG_ON y el pánico del kernel) mediante el establecimiento de una conexión RDS con la dirección IP de origen igual a la dirección de la interfaz IPoIB IP propia, como lo demuestra rds-ping. • http://marc.info/?l=bugtraq&m=139447903326211&w=2 http://rhn.redhat.com/errata/RHSA-2012-0743.html http://rhn.redhat.com/errata/RHSA-2012-1540.html http://ubuntu.com/usn/usn-1529-1 http://www.securityfocus.com/bid/54062 http://www.ubuntu.com/usn/USN-1555-1 http://www.ubuntu.com/usn/USN-1556-1 https://bugzilla.redhat.com/show_bug.cgi?id=822754 https://oss.oracle.com/git/?p=redpatch.git%3Ba=commit%3Bh=c7b6a0a1d8d636852be130fa15fa8be10d4704e8 https://www.suse •
CVE-2012-2375 – kernel: incomplete fix for CVE-2011-4131
https://notcve.org/view.php?id=CVE-2012-2375
The __nfs4_get_acl_uncached function in fs/nfs/nfs4proc.c in the NFSv4 implementation in the Linux kernel before 3.3.2 uses an incorrect length variable during a copy operation, which allows remote NFS servers to cause a denial of service (OOPS) by sending an excessive number of bitmap words in an FATTR4_ACL reply. NOTE: this vulnerability exists because of an incomplete fix for CVE-2011-4131. La función __nfs4_get_acl_uncached de fs/nfs/nfs4proc.c de la implementación NFSv4 del kernel de Linux en versiones anteriores a la 3.3.2 utiliza una variable de longitud incorrecta durante una operación de copia, lo que permite a servidores NFS remotos provocar una denegación de servicio (OOPS) enviando un número excesivo de bitmap words en una respuesta FATTR4_ACL. NOTA: esta vulnerabilida existe debido a una solución incompleta de CVE-2011-4131. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=20e0fa98b751facf9a1101edaefbc19c82616a68 http://marc.info/?l=bugtraq&m=139447903326211&w=2 http://rhn.redhat.com/errata/RHSA-2012-1580.html http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.3.2 http://www.openwall.com/lists/oss-security/2012/05/18/13 https://bugzilla.redhat.com/show_bug.cgi?id=822869 https://github.com/torvalds/linux/commit/20e0fa98b751facf9a1101edaefbc19c82616a68 https://access • CWE-189: Numeric Errors •
CVE-2012-2390 – kernel: huge pages: memory leak on mmap failure
https://notcve.org/view.php?id=CVE-2012-2390
Memory leak in mm/hugetlb.c in the Linux kernel before 3.4.2 allows local users to cause a denial of service (memory consumption or system crash) via invalid MAP_HUGETLB mmap operations. Memoria no liberada (memory leak) en mm/hugetlb.c del kernel de Linux en versiones anteriores a la 3.4.2.
