Vulnerabilities > CVE-2008-3247 - Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Linux Kernel
Attack vector
UNKNOWN Attack complexity
UNKNOWN Privileges required
UNKNOWN Confidentiality impact
UNKNOWN Integrity impact
UNKNOWN Availability impact
UNKNOWN Summary
The LDT implementation in the Linux kernel 2.6.25.x before 2.6.25.11 on x86_64 platforms uses an incorrect size for ldt_desc, which allows local users to cause a denial of service (system crash) or possibly gain privileges via unspecified vectors.
Vulnerable Configurations
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.

NASL family Fedora Local Security Checks NASL id FEDORA_2008-8980.NASL description Update kernel from version 2.6.26.5 to 2.6.26.6: http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.26.6 CVE-2008-3831 An IOCTL in the i915 driver was not properly restricted to users with the proper capabilities to use it. CVE-2008-4410 The vmi_write_ldt_entry function in arch/x86/kernel/vmi_32.c in the Virtual Machine Interface (VMI) in the Linux kernel 2.6.26.5 invokes write_idt_entry where write_ldt_entry was intended, which allows local users to cause a denial of service (persistent application failure) via crafted function calls, related to the Java Runtime Environment (JRE) experiencing improper LDT selector state, a different vulnerability than CVE-2008-3247. CVE-2008-3525 The sbni_ioctl function in drivers/net/wan/sbni.c in the wan subsystem in the Linux kernel 2.6.26.3 does not check for the CAP_NET_ADMIN capability before processing a (1) SIOCDEVRESINSTATS, (2) SIOCDEVSHWSTATE, (3) SIOCDEVENSLAVE, or (4) SIOCDEVEMANSIPATE ioctl request, which allows local users to bypass intended capability restrictions. CVE-2008-4554 The do_splice_from function in fs/splice.c in the Linux kernel before 2.6.27 does not reject file descriptors that have the O_APPEND flag set, which allows local users to bypass append mode and make arbitrary changes to other locations in the file. CVE-2008-4576 sctp in Linux kernel before 2.6.25.18 allows remote attackers to cause a denial of service (OOPS) via an INIT-ACK that states the peer does not support AUTH, which causes the sctp_process_init function to clean up active transports and triggers the OOPS when the T1-Init timer expires.
