1) Resource management errors

EUVDB-ID: #VU95247

Risk: Low

CVSSv3.1: 3 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L/E:P/RL:O/RC:C]

CVE-ID: CVE-2005-2800

CWE-ID: CWE-399 - Resource Management Errors

Exploit availability: Yes

Description

The vulnerability allows a local user to perform service disruption.

Memory leak in the seq_file implementation in the SCSI procfs interface (sg.c) in Linux kernel 2.6.13 and earlier allows local users to cause a denial of service (memory consumption) via certain repeated reads from the /proc/scsi/sg/devices file, which is not properly handled when the next() iterator returns NULL or an error.

Mitigation

Install update from vendor's repository.
