Detailsinfo

A vulnerability was found in ncompress 4.2.4. It has been rated as critical. This issue affects the function comprexx of the component FTP Server. The manipulation of the argument filename with an unknown input leads to a stack-based overflow vulnerability. Using CWE to declare the problem leads to CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Stack-based buffer overflow in the comprexx function for ncompress 4.2.4 and earlier, when used in situations that cross security boundaries (such as FTP server), may allow remote attackers to execute arbitrary code via a long filename argument.

The bug was discovered 11/20/2001. The weakness was released 12/23/2004 by Pavel Kankovsky as confirmed advisory (CERT.org). It is possible to read the advisory at kb.cert.org.
