Sun SunOS 4.1.3u1/4.1.4 lpr memory corruption

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability was found in Sun SunOS 4.1.3u1/4.1.4 (Operating System). It has been rated as critical. This issue affects an unknown function of the component lpr. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

buffer overflow in lpr as used in bsd-based systems including linux allows local users to execute arbitrary code as root via a long -c (classification) command line option.

The weakness was shared 08/13/1996 by bloodmask as not defined posting (Bugtraq). The advisory is shared at The identification of this vulnerability is CVE-1999-0032. The exploitation is known to be easy. An attack has to be approached locally. No form of authentication is needed for a successful exploitation. Technical details are unknown but a public exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 05/07/2019). It is expected to see the exploit prices for this product decreasing in the near future.Due to its background and reception, this vulnerability has a historic impact.
