    Package : krb5
    CVE ID : CVE-2015-2695 CVE-2015-2696 CVE-2015-2697
    Debian Bug : 803083 803084 803088

    Several vulnerabilities were discovered in krb5, the MIT implementation
    of Kerberos. The Common Vulnerabilities and Exposures project identifies
    the following problems:

    CVE-2015-2695

    It was discovered that applications which call gss_inquire_context()
    on a partially-established SPNEGO context can cause the GSS-API
    library to read from a pointer using the wrong type, leading to a
    process crash.

    CVE-2015-2696

    It was discovered that applications which call gss_inquire_context()
    on a partially-established IAKERB context can cause the GSS-API
    library to read from a pointer using the wrong type, leading to a
    process crash.

    CVE-2015-2697

    It was discovered that the build_principal_va() function incorrectly
    handles input strings. An authenticated attacker can take advantage
    of this flaw to cause a KDC to crash using a TGS request with a
    large realm field beginning with a null byte.

    For the oldstable distribution (wheezy), these problems have been fixed
    in version 1.10.1+dfsg-5+deb7u4.

    For the stable distribution (jessie), these problems have been fixed in
    version 1.12.1+dfsg-19+deb8u1.

    For the testing distribution (stretch), these problems have been fixed
    in version 1.13.2+dfsg-3.

    For the unstable distribution (sid), these problems have been fixed in
    version 1.13.2+dfsg-3.

    We recommend that you upgrade your krb5 packages.
