Ubuntu 7.10 / 8.04 LTS : pidgin vulnerabilities (USN-675-1)

Medium Nessus Plugin ID 36899


The remote Ubuntu host is missing one or more security-related patches.


It was discovered that Pidgin did not properly handle certain malformed messages in the MSN protocol handler. A remote attacker could send a specially crafted message and possibly execute arbitrary code with user privileges. (CVE-2008-2927)

It was discovered that Pidgin did not properly handle file transfers containing a long filename and special characters in the MSN protocol handler. A remote attacker could send a specially crafted filename in a file transfer request and cause Pidgin to crash, leading to a denial of service. (CVE-2008-2955)

It was discovered that Pidgin did not impose resource limitations in the UPnP service. A remote attacker could cause Pidgin to download arbitrary files and cause a denial of service from memory or disk space exhaustion. (CVE-2008-2957)

It was discovered that Pidgin did not validate SSL certificates when using a secure connection. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could be exploited to view sensitive information. This update alters Pidgin behaviour by asking users to confirm the validity of a certificate upon initial login.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
