TurboLinux Security Announcement
Package: All packages prior to LPRng-3.6.26
Date: Tuesday, 01-30-2001 5:00 PDT
Affected TurboLinux versions: All versions of TurboLinux
6.0.5 and earlier
TurboLinux Advisory ID#: TLSA2001001-1
Credits: Reported to BugTraq by Chris Evans
A security hole was discovered in the package mentioned above.
Please update the package in your installation as soon as
possible.
1. Problem Summary(From the FreeBSD, Inc. Advisory)
The LPRng port, versions prior to 3.6.26, contains a potential
vulnera- bility which may allow root compromise from both local and
remote systems. The vulnerability is due to incorrect usage of the
syslog(3) function. Local and remote users can send
string-formatting operators to the print- er daemon to corrupt the
daemon’s execution, potentially gaining root access.
2. Impact(From the FreeBSD, Inc. Advisory)
Local and remote users may potentially gain root privileges on
systems using LPRng.
If you have not chosen to install the LPRng port/package, then
your system is not vulnerable to this problem.
3. Solution
Update the package from our ftp server by running the following
command:
rpm -Uvh –nodeps –force ftp_path_to_filename
Where ftp_path_to_filename is the following:
ftp://ftp.turbolinux.com/pub/updates/6.0/security/LPRng-3.6.26-1.i386.rpm
The source RPM can be downloaded here:
ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/LPRng-3.6.26-1.src.rpm
**Note: You must rebuild and install the RPM if you choose to
download and install the SRPM. Simply installing the SRPM alone
WILL NOT CLOSE THE SECURITY HOLE.
Please verify the MD5 checksums of the updates before you
install:
