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.

(CVE-2008-3496) 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-2008-3525) Integer overflow in the sctp_setsockopt_auth_key function in net/sctp/socket.c in the Stream Control Transmission Protocol (sctp) implementation in the Linux kernel 2.6.24-rc1 through 2.6.26.3 allows remote attackers to cause a denial of service (panic) or possibly have unspecified other impact via a crafted sca_keylength field associated with the SCTP_AUTH_KEY option. (CVE-2008-3526) The sctp_auth_ep_set_hmacs function in net/sctp/auth.c in the Stream Control Transmission Protocol (sctp) implementation in the Linux kernel before 2.6.26.4, when the SCTP-AUTH extension is enabled, does not verify that the identifier index is within the bounds established by SCTP_AUTH_HMAC_ID_MAX, which allows local users to obtain sensitive information via a crafted SCTP_HMAC_IDENT IOCTL request involving the sctp_getsockopt function, a different vulnerability than CVE-2008-4113. (CVE-2008-4445) Additionaly, fixes for sound on NEC Versa S9100 and others were added, PATA and AHCI support for Intel ICH10 was added, a fix to allow better disk transfer speeds was made for Hercules EC-900 mini-notebook, a cyrus-imapd corruption issue in x86_64 arch was solved, RealTek 8169/8168/8101 support was improved, and a few other things.

| statement | Not vulnerable. This issue did not affect the versions of Linux kernel as shipped with Red Hat Enterprise Linux 2.1, 3, 4, 5 or Red Hat Enterprise MRG. The uvcvideo driver was first added in kernel packages update RHSA-2009:0225 in Red Hat Enterprise Linux 5.3, and it already contained a fix for this flaw. |
