DESCRIPTION:
A weakness and a vulnerability have been reported in TimThumb, which
can be exploited by malicious people to bypass certain security
restrictions and compromise a vulnerable system.
1) The application does not properly store content in the cache
directory when processing input passed via the "src" parameter, which
can be exploited to e.g. upload and execute arbitrary PHP files.
The vulnerability is reported in versions prior to 1.33.
2) The application does not properly verify domain names passed via
the "src" parameter, which can be exploited to bypass the allowed
sites filter by providing a specially crafted domain.
The weakness is reported in versions prior to 1.34.
SOLUTION:
Update to version 1.34.
PROVIDED AND/OR DISCOVERED BY:
