Debian Security Advisory DSA-3395-1 [email protected]

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.
