Hi All, I'm sure you've all heard about the bash vulnerability where: *"specially-crafted environment variables can be used to inject shell commands" unearthed by Stephane Chazelas very recently?.
Many linux flavors have already released patches and according to the following test (see in full at: https://access.redhat.com/articles/1200223) Solaris 10 at least appears to be vulnerable. ========================= Diagnostic Steps To test if your version of Bash is vulnerable to this issue, run the following command: $ env x='() { :;}; echo vulnerable' bash -c "echo this is a test" If the output of the above command looks as follows: vulnerable this is a test you are using a vulnerable version of Bash. The patch used to fix this issue ensures that no code is allowed after the end of a Bash function. Thus, if you run the above example with the patched version of Bash, you should get an output similar to: $ env x='() { :;}; echo vulnerable' bash -c "echo this is a test" bash: warning: x: ignoring function definition attempt bash: error importing function definition for `x' this is a test ========================= Does anyone know if there is, or is planned, a patch for Solaris' bash implementation?. * https://access.redhat.com/security/cve/CVE-2014-6271?sc_cid=70160000000e8eaAAA&; -- Cheers, Tony. \|/ ____ \|/ @~/ ,. \~@ /_( \__/ )_\ +------------------------------\__U_/----------------------------------+
