CVE-2013-0271 pidgin: MXit protocol insufficient sanitization of saved image file names
Last modified: 2013-03-04 01:40:45 EST
A security flaw was found in the way MXit protocol plug-in of libPurple generated temporary file used for image data storage, when processing Imagestrip MXit command. A rogue server or remote attacker could use this flaw to specify a file name, which in a partial manner would be used to generate the final local path, used for storage of image data on the local disk, possibly leading to attacker's ability to overwrite local files accessible with the privileges of the user running the pidgin executable.
