Vulnerability CVE-2017-17840


Published: 2017-12-27

Description:
An issue was discovered in Open-iSCSI through 2.0.875. A local attacker can cause the iscsiuio server to abort or potentially execute code by sending messages with incorrect lengths, which (due to lack of checking) can lead to buffer overflows, and result in aborts (with overflow checking enabled) or code execution. The process_iscsid_broadcast function in iscsiuio/src/unix/iscsid_ipc.c does not validate the payload length before a write operation.

Type:

CWE-119

(Improper Restriction of Operations within the Bounds of a Memory Buffer)

Vendor: Open-iscsi project
Product: Open-iscsi 
Version: 2.0.875;
