| Description: | Joel Becker discovered that OCFS2 did not correctly validate on-disk symlink structures. If an attacker were able to trick a user or automated system into mounting a specially crafted filesystem, it could crash the system or exposde kernel memory, leading to a loss of privacy. Al Viro discovered a race condition in the TTY driver. A local attacker could exploit this to crash the system, leading to a denial of service. Dan Rosenberg discovered that the MOVE_EXT ext4 ioctl did not correctly check file permissions. A local attacker could overwrite append-only files, leading to potential data loss. Dan Rosenberg discovered that the swapexit xfs ioctl did not correctly check file permissions. A local attacker could exploit this to read from write-only files, leading to a loss of privacy. Suresh Jayaraman discovered that CIFS did not correctly validate certain response packats. A remote attacker could send specially crafted traffic that would crash the system, leading to a denial of service. Ben Hutchings discovered that the ethtool interface did not correctly check certain sizes. A local attacker could perform malicious ioctl calls that could crash the system, leading to a denial of service. James Chapman discovered that L2TP did not correctly evaluate checksum capabilities. If an attacker could make malicious routing changes, they could crash the system, leading to a denial of service. Neil Brown discovered that NFSv4 did not correctly check certain write requests. A remote attacker could send specially crafted traffic that could crash the system or possibly gain root privileges. David Howells discovered that DNS resolution in CIFS could be spoofed. A local attacker could exploit this to control DNS replies, leading to a loss of privacy and possible privilege escalation. Bob Peterson discovered that GFS2 rename operations did not correctly validate certain sizes. A local attacker could exploit this to crash the system, leading to a denial of service. Eric Dumazet discovered that many network functions could leak kernel stack contents. A local attacker could exploit this to read portions of kernel memory, leading to a loss of privacy. Sergey Vlasov discovered that JFS did not correctly handle certain extended attributes. A local attacker could bypass namespace access rules, leading to a loss of privacy. Tavis Ormandy discovered that the IRDA subsystem did not correctly shut down. A local attacker could exploit this to cause the system to crash or possibly gain root privileges. Brad Spengler discovered that the wireless extensions did not correctly validate certain request sizes. A local attacker could exploit this to read portions of kernel memory, leading to a loss of privacy. Tavis Ormandy discovered that the session keyring did not correctly check for its parent. On systems without a default session keyring, a local attacker could exploit this to crash the system, leading to a denial of service. Kees Cook discovered that the V4L1 32bit compat interface did not correctly validate certain parameters. A local attacker on a 64bit system with access to a video device could exploit this to gain root privileges. Toshiyuki Okajima discovered that ext4 did not correctly check certain parameters. A local attacker could exploit this to crash the system or overwrite the last block of large files. Tavis Ormandy discovered that the AIO subsystem did not correctly validate certain parameters. A local attacker could exploit this to crash the system or possibly gain root privileges. Dan Rosenberg discovered that certain XFS ioctls leaked kernel stack contents. A local attacker could exploit this to read portions of kernel memory, leading to a loss of privacy. Tavis Ormandy discovered that the OSS sequencer device did not correctly shut down. A local attacker could exploit this to crash the system or possibly gain root privileges. Dan Rosenberg discovered that the ROSE driver did not correctly check parameters. A local attacker with access to a ROSE network device could exploit this to crash the system or possibly gain root privileges. Thomas Dreibholz discovered that SCTP did not correctly handle appending packet chunks. A remote attacker could send specially crafted traffic to crash the system, leading to a denial of service. Dan Rosenberg discovered that the CD driver did not correctly check parameters. A local attacker could exploit this to read arbitrary kernel memory, leading to a loss of privacy. Dan Rosenberg discovered that the Sound subsystem did not correctly validate parameters. A local attacker could exploit this to crash the system, leading to a denial of service. Dan Rosenberg discovered that SCTP did not correctly handle HMAC calculations. A remote attacker could send specially crafted traffic that would crash the system, leading to a denial of service. Dan Rosenberg discovered that the RDS network protocol did not correctly check certain parameters. A local attacker could exploit this gain root privileges |
