    Multiple vulnerabilities have been discovered in lintian,
    a Debian package checker. The following Common Vulnerabilities and
    Exposures project ids have been assigned to identify them:
    
    CVE-2009-4013: missing control files sanitation
    
        Control field names and values were not sanitised before using them
        in certain operations that could lead to directory traversals.
    
        Patch systems' control files were not sanitised before using them
        in certain operations that could lead to directory traversals.
    
        An attacker could exploit these vulnerabilities to overwrite
        arbitrary files or disclose system information.
    
    CVE-2009-4014: format string vulnerabilities
    
        Multiple check scripts and the Lintian::Schedule module were using
        user-provided input as part of the sprintf/printf format string.
    
    CVE-2009-4015: arbitrary command execution
    
        File names were not properly escaped when passing them as arguments
        to certain commands, allowing the execution of other commands as
        pipes or as a set of shell commands.
    
    
    For the oldstable distribution (etch), these problems have been fixed in
    version 1.23.28+etch1.
    
    For the stable distribution (lenny), these problems have been fixed in
    version 1.24.2.1+lenny1.
    
    For the testing distribution (squeeze), these problems will be fixed
    soon.
    
    For the unstable distribution (sid), these problems have been fixed in
    version 2.3.2
    
    
    We recommend that you upgrade your lintian packages.
    
    Upgrade instructions
