|

Description:
Some vulnerabilities have been reported in the mod_tcl module for Apache HTTP server, which can be exploited by malicious people to compromise a vulnerable system.
The vulnerabilities are caused due to format string errors in tcl_cmds.c and tcl_core.c when calling the "set_var()" function with user-supplied input. This can be exploited by sending a specially crafted request containing format specifiers.
Successful exploitation allows execution of arbitrary code, but requires knowledge of the location of a tcl server script configured to use the vulnerable module for processing.
Solution:
Update to version 1.0.1.
