USN-852-1 -- Linux kernel vulnerabilities

ID: oval:org.secpod.oval:def:700430Date: (C)2011-05-13   (M)2017-10-04
Class: PATCHFamily: unix




Solar Designer discovered that the z90crypt driver did not correctly check capabilities. A local attacker could exploit this to shut down the device, leading to a denial of service. Only affected Ubuntu 6.06. Michael Buesch discovered that the SGI GRU driver did not correctly check the length when setting options. A local attacker could exploit this to write to the kernel stack, leading to root privilege escalation or a denial of service. Only affected Ubuntu 8.10 and 9.04. It was discovered that SELinux did not fully implement the mmap_min_addr restrictions. A local attacker could exploit this to allocate the NULL memory page which could lead to further attacks against kernel NULL-dereference vulnerabilities. Ubuntu 6.06 was not affected. Cagri Coltekin discovered that the UDP stack did not correctly handle certain flags. A local user could send specially crafted commands and traffic to gain root privileges or crash the systeam, leading to a denial of service. Only affected Ubuntu 6.06. Hiroshi Shimamoto discovered that monotonic timers did not correctly validate parameters. A local user could make a specially crafted timer request to gain root privileges or crash the system, leading to a denial of service. Only affected Ubuntu 9.04. Michael Buesch discovered that the HPPA ISA EEPROM driver did not correctly validate positions. A local user could make a specially crafted request to gain root privileges or crash the system, leading to a denial of service. Ulrich Drepper discovered that kernel signal stacks were not being correctly padded on 64-bit systems. A local attacker could send specially crafted calls to expose 4 bytes of kernel stack memory, leading to a loss of privacy. Jens Rosenboom discovered that the clone method did not correctly clear certain fields. A local attacker could exploit this to gain privileges or crash the system, leading to a denial of service. It was discovered that the MD driver did not check certain sysfs files. A local attacker with write access to /sys could exploit this to cause a system crash, leading to a denial of service. Ubuntu 6.06 was not affected. Mark Smith discovered that the AppleTalk stack did not correctly manage memory. A remote attacker could send specially crafted traffic to cause the system to consume all available memory, leading to a denial of service. Loïc Minier discovered that eCryptfs did not correctly handle writing to certain deleted files. A local attacker could exploit this to gain root privileges or crash the system, leading to a denial of service. Ubuntu 6.06 was not affected. It was discovered that the LLC, AppleTalk, IR, EConet, Netrom, and ROSE network stacks did not correctly initialize their data structures. A local attacker could make specially crafted calls to read kernel memory, leading to a loss of privacy. It was discovered that the randomization used for Address Space Layout Randomization was predictable within a small window of time. A local attacker could exploit this to leverage further attacks that require knowledge of userspace memory layouts. Eric Paris discovered that NFSv4 did not correctly handle file creation failures. An attacker with write access to an NFSv4 share could exploit this to create files with arbitrary mode bits, leading to privilege escalation or a loss of privacy. Bob Tracy discovered that the SCSI generic driver did not correctly use the right index for array access. A local attacker with write access to a CDR could exploit this to crash the system, leading to a denial of service. Only Ubuntu 9.04 was affected. Jan Kiszka discovered that KVM did not correctly validate certain hypercalls. A local unprivileged attacker in a virtual guest could exploit this to crash the guest kernel, leading to a denial of service. Ubuntu 6.06 was not affected
