Vulnerabilities > CVE-2009-3288 - Improper Restriction of Operations Within the Bounds of A Memory Buffer vulnerability in multiple products
Attack vector
LOCAL Attack complexity
LOW Privileges required
NONE Confidentiality impact
NONE Integrity impact
NONE Availability impact
COMPLETE Summary
The sg_build_indirect function in drivers/scsi/sg.c in Linux kernel 2.6.28-rc1 through 2.6.31-rc8 uses an incorrect variable when accessing an array, which allows local users to cause a denial of service (kernel OOPS and NULL pointer dereference), as demonstrated by using xcdroast to duplicate a CD. NOTE: this is only exploitable by users who can open the cdrom device.

Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

| description | 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. (CVE-2009-1883) 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. (CVE-2009-2584) 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. (CVE-2009-2695) 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. (CVE-2009-2698) 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. (CVE-2009-2767) 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. (CVE-2009-2846) 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. (CVE-2009-2847) 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. (CVE-2009-2848) 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. (CVE-2009-2849) 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. (CVE-2009-2903) Loic 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. (CVE-2009-2908) 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. (CVE-2009-3001, CVE-2009-3002) 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. (CVE-2009-3238) 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. (CVE-2009-3286) 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. (CVE-2009-3288) 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. (CVE-2009-3290). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues. |
