Package : krb5 Version : 1.8.3+dfsg-4squeeze10 CVE ID : CVE-2015-2695 CVE-2015-2697
Several vulnerabilities were discovered in krb5, the MIT implementation of Kerberos. The Common Vulnerabilities and Exposures project identifies the following problems:
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.
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 oldoldstable distribution (squeeze), these problems have been fixed in version 1.8.3+dfsg-4squeeze10.
We recommend that you upgrade your krb5 packages.
