Descriptions

The Linux kernel 2.6.33.2 and earlier, when a ReiserFS filesystem exists, does not restrict read or write access to the .reiserfs_priv directory, which allows local users to gain privileges by modifying (1) extended attributes or (2) ACLs, as demonstrated by deleting a file under .reiserfs_priv/xattrs/.

El kernel de Linux v2.6.33.2 y anteriores, cuando esta sobre un sistema de fichero ReiserFS, no restringe adecuadamente la lectura o escritura al directorio .reiserfs_priv, lo que permite a usuarios locales conseguir privilegios mediante la modificación de (1) atributos extendidos o (2) ACLs, como se demuestra mediante el borrado de un fichero bajo .reiserfs_priv/xattrs/.

It was discovered that the Linux kernel did not correctly handle memory protection of the Virtual Dynamic Shared Object page when running a 32-bit application on a 64-bit kernel. It was discovered that the r8169 network driver did not correctly check the size of Ethernet frames. Wei Yongjun discovered that SCTP did not correctly validate certain chunks. It was discovered that KVM did not correctly limit certain privileged IO accesses on x86. Evgeniy Polyakov discovered that IPv6 did not correctly handle certain TUN packets. Tons of other vulnerabilities have also been discovered and addressed.
