Title: Solaris PAM & unix_scheme Vulnerability
Severity: MODERATE
Description:
There is a buffer overflow condition on arguments in Pluggable Authentication Modules (PAM) and unix_scheme (5.4 and 5.3). Therefore, an unauthorized user could exploit this vulnerability via the passwd program to gain root access. Under SunOS 5.5.1, 5.5.1_x86, 5.5, 5.5_x86, yppasswd and nispasswd are hard links to the passwd program and therefore are also vulnerable. Under SunOS 5.4 and 5.3, passwd, yppasswd, and nispasswd are separate programs but they dynamically link unix_scheme and are affected.
Affected Products:
- Sun Solaris 2.3.0
- Sun Solaris 2.4.0
- Sun Solaris 2.4.0_x86
- Sun Solaris 2.5.0
- Sun Solaris 2.5.0_x86
