Linux Audit audit_log_user_command() buffer overflow
| linuxaudit-auditlogusercommand-bo (41576) |  High Risk |
Description:
Linux Audit is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the audit_log_user_command() function. By sending an overly long command argument, a local attacker could overflow a buffer and execute arbitrary code on the system with libaudit privileges, or cause the application to crash.
Platforms Affected:
- Gentoo, Linux
- MandrakeSoft, Mandrake Linux 2008.0 X86_64
- MandrakeSoft, Mandrake Linux 2008.0
- MandrakeSoft, Mandrake Linux 2008.1 X86_64
- MandrakeSoft, Mandrake Linux 2008.1
- Steve Grubb, Linux Audit prior to 1.7
Remedy:
Upgrade to the latest version of Linux Audit (1.7 or later), available from the Linux Audit Web page. See References.
Consequences:
Gain Privileges
