Title: Davin McCall dlogin Buffer Overflow Vulnerability
Severity: HIGH
Description:
dlogin is a replacement for the Unix login utility, targetted at home users of Linux systems. It supports a variety of convenience features for local console users, including the ability to log onto additional virtual terminals without the need to reauthenticate, and allowing local console users to perform a variety of system tasks without the need to authenticate as root.
A vulnerability exists in some versions of dlogin. It is possible to overflow a buffer. While further details are not currently available, overflows may lead to stack corruption, and to eventual execution of arbitrary code.
While dlogin does not have to be installed suid root, login processes would normally execute as the root user.
Affected Products:
- Davin McCall dlogin 1.0.0a
