>Synopsis: memory bug / potential buffer overflow problem
>Severity: non-critical
>Priority: medium
>Category: cvs
>Class: sw-bug
>Release: 1.11.1p1
>Environment:
System: Linux nox.lemuria.org 2.4.17 #1 Fri May 3 11:38:12 CEST 2002 i686 unknown
Architecture: i686
>Description:
on login failures, lines like the following appear in the syslog:
cvs: login failure by tom / �^F^W@�^F^W@^P (for /home/cvs)
it should be obvious that the part behind the / is not any actual data, so it
most likely is grabbing into a wrong memory area there.
if the data that should be there is remotely-supplied (password? servername?)
it may be possible to exploit this.
>How-To-Repeat:
install cvs, use pserver, fail login
works everytime for me
>Fix:
