    Debian Bug      
    
    Multiple vulnerabilities were discovered in libssh by Florian Weimer and Xi
    Wang:
    
    CVE-2012-4559: multiple double free() flaws
    CVE-2012-4561: multiple invalid free() flaws
    CVE-2012-4562: multiple improper overflow checks
    
    Those could lead to a denial of service by making an ssh client linked to
    libssh crash, and maybe even arbitrary code execution.
    
    For the stable distribution (squeeze), these problems have been fixed in
    version 0.4.5-3+squeeze1.
    
    For the testing distribution (wheezy), these problems have been fixed in
    version 0.5.3-1.
    
    For the unstable distribution (sid), these problems have been fixed in
    version 0.5.3-1.
    
    We recommend that you upgrade your libssh packages.
