    Hi all,
    
    it seems that cvs (version 1.10.7 from Debians stable repos) has a
    bufferoverflow but I'm but sure if it's exploitable
    
    ls -la /usr/bin/cvs
    -rwxr-xr-x    1 root     root       490160 Mar 22  2000 /usr/bin/cvs
    
    no suid bit but it's owned by root
    
    cvs diff -C`perl -e "print 'a' x 300"` tables.sql
    
    Index: tables.sql
    ===================================================================
    RCS file: /opt/CVSROOT/procedit/sql/tables.sql,v
    retrieving revision 1.1
    diff -u -3 -p
    -Caaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa-r1.1 tables.sql
    cvs diff: context length specified twice
    Segmentation fault (core dumped)
    
    but couldn't it help someone to get access to the system ?
    
    Best regards
    Kim
