pidgin vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 10.04 LTS

Summary:

Several security issues were fixed in Pidgin.

Software Description:
- pidgin: graphical multi-protocol instant messaging client for X

Details:

Chris Wysopal discovered that Pidgin incorrectly handled file transfers in
the MXit protocol handler. A remote attacker could use this issue to create
or overwrite arbitrary files. This issue only affected Ubuntu 11.10,
Ubuntu 12.04 LTS and Ubuntu 12.10. (CVE-2013-0271)

It was discovered that Pidgin incorrectly handled long HTTP headers in the
MXit protocol handler. A malicious remote server could use this issue to
execute arbitrary code. (CVE-2013-0272)

It was discovered that Pidgin incorrectly handled long user IDs in the
Sametime protocol handler. A malicious remote server could use this issue
to cause Pidgin to crash, resulting in a denial of service. (CVE-2013-0273)

It was discovered that Pidgin incorrectly handled long strings when
processing UPnP responses. A remote attacker could use this issue to cause
Pidgin to crash, resulting in a denial of service. (CVE-2013-0274)
