Secunia Advisory SA11817

Where:

From remote

Impact:

DoS, System access

Solution Status:

Vendor Patch

CVE Reference(s):

Description


Multiple vulnerabilities have been reported in CVS, which can be exploited by malicious users to cause a DoS (Denial of Service) or compromise a vulnerable system.

1) An NULL-termination error within the patch for the previous "Entry" line heap-based buffer overflow vulnerability can potentially be exploited to crash a vulnerable server.

2) A "double free" error can reportedly be exploited via the "Argumentx" command to execute arbitrary code on a vulnerable system.

3) A format string error within the processing of the CVS wrapper file can potentially be exploited to execute arbitrary code on a vulnerable system by including a specially crafted line containing format specifiers. However, successful exploitation requires CVSROOT commit access.

4) An integer overflow within the handling of the "Max-dotdot" CVS protocol command can be exploited to crash the CVS server and consume available disk space.

5) An boundary error within the "serve_notify()" function when handling empty data lines can potentially be exploited to execute arbitrary code.

6) Some underflow errors exist when reading configuration files containing empty lines from CVSROOT. Successful exploitation requires CVSROOT commit access, and the impact is unknown.

7) Various integer multiplication overflows may potentially be exploited for arbitrary code execution.


Solution:
The vulnerabilities have been fixed in CVS Feature Version 1.12.9 and CVS Stable Version 1.11.17.
