CVE-2017-1000410

High
Published: Translated: NVD NIST

Summary

The Linux kernel version 3.3-rc1 and later is affected by a vulnerability related to the processing of incoming L2CAP commands - ConfigRequest and ConfigResponse messages. This info leak is a result of uninitialized stack variables that may be returned to an attacker in their uninitialized state.

Risk Assessment

An attacker can exploit this vulnerability to bypass KASLR and stack canaries protection, increasing the risk of gaining control over the system. Combining this vulnerability with others, such as CVE-2017-1000251, may allow for remote code execution.

Recommendation

It is recommended to update the Linux kernel to the latest version to mitigate this vulnerability and to monitor systems for potential exploitation attempts.

Original NVD description (English source)

The Linux kernel version 3.3-rc1 and later is affected by a vulnerability lies in the processing of incoming L2CAP commands - ConfigRequest, and ConfigResponse messages. This info leak is a result of uninitialized stack variables that may be returned to an attacker in their uninitialized state. By manipulating the code flows that precede the handling of these configuration messages, an attacker can also gain some control over which data will be held in the uninitialized stack variables. This can allow him to bypass KASLR, and stack canaries protection - as both pointers and stack canaries may be leaked in this manner. Combining this vulnerability (for example) with the previously disclosed RCE vulnerability in L2CAP configuration parsing (CVE-2017-1000251) may allow an attacker to exploit the RCE against kernels which were built with the above mitigations. These are the specifics of this vulnerability: In the function l2cap_parse_conf_rsp and in the function l2cap_parse_conf_req the fo
