Quoting GLSA 200803-31:
"Venustech AD-LAB discovered multiple vulnerabilities in the GSSAPI library: usage of a freed variable in the gss_indicate_mechs() function (CVE-2007-5901) and a double free() vulnerability in the gss_krb5int_make_seal_token_v3() function (CVE-2007-5971)."

Quoting MDVSA-2008:069:
"Multiple memory management flaws were found in the GSSAPI library
used by Kerberos that could result in the use of already freed memory
or an attempt to free already freed memory, possibly leading to a
crash or allowing the execution of arbitrary code (CVE-2007-5901,
CVE-2007-5971)."

The CVEs addressed in this bug have been resolved in the version now uploaded to hardy (1.6.dfsg.3~beta1-2ubuntu1). However, that version should be backported to the remaining supported releases.
