util-linux-ng login data manipulation
| utillinuxng-login-data-manipulation (41987) |  Low Risk |
Description:
util-linux-ng could allow a remote attacker to manipulate data, caused by an argument injection vulnerability in login-utils/login.c. By editing portions of log events, a remote attacker could exploit this vulnerability to hide activities and possibly insert arbitrary data into the audit log.
Platforms Affected:
- Kernel, util-linux 2.11h
- Kernel, util-linux 2.11i
- Kernel, util-linux 2.11k
- Kernel, util-linux 2.11l
- Kernel, util-linux 2.12a
- Kernel, util-linux 2.12r
- Kernel, util-linux 2.13-pre1
- Kernel, util-linux 2.13-pre2
- Kernel, util-linux 2.14
- MandrakeSoft, Mandrake Linux 2008.0
- MandrakeSoft, Mandrake Linux 2008.0 X86_64
- MandrakeSoft, Mandrake Linux 2008.1
- MandrakeSoft, Mandrake Linux 2008.1 X86_64
- RedHat, Enterprise Linux 4 AS
- RedHat, Enterprise Linux 4 WS
- RedHat, Enterprise Linux 4 Desktop
- RedHat, Enterprise Linux 4 ES
Remedy:
Upgrade to the latest version of util-linux-ng (2.13.1.1 or later), available from the util-linux Web page. See References.
Consequences:
Gain Access
