- ------------------------------------------------------------------------- Debian Security Advisory DSA-2271-1 security@debian.org http://www.debian.org/security/ Giuseppe Iuculano July 02, 2011 http://www.debian.org/security/faq - -------------------------------------------------------------------------
Package : curl Vulnerability : improper delegation of client credentials Problem type : remote Debian-specific: no CVE ID : CVE-2011-2192 Debian Bug : #631615
Richard Silverman discovered that when doing GSSAPI authentication, libcurl unconditionally performs credential delegation. This hands the server a copy of the client's security credentials, allowing the server to impersonate the client to any other using the same GSSAPI mechanism. This is obviously a very sensitive operation, which should only be done when the user explicitly so directs.
For the oldstable distribution (lenny), this problem has been fixed in version 7.18.2-8lenny5.
For the stable distribution (squeeze), this problem has been fixed in version 7.21.0-2.
For the testing distribution (wheezy), this problem has been fixed in version 7.21.6-2.
For the unstable distribution (sid), this problem has been fixed in version 7.21.6-2.
We recommend that you upgrade your curl packages.
