A vulnerability, which was classified as very critical, has been found in Sun Solaris 2.4/2.5.1 (Operating System). This issue affects some unknown processing of the component nlps_server. The manipulation with the input value NLPS:002:002: 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 nlps_server in Sun Solaris x86 2.4, 2.5, and 2.5.1 allows remote attackers to execute arbitrary code as root via a long string beginning with "NLPS:002:002:" to the listen (aka System V listener) port, TCP port 2766.
