Synopsis

The remote Fedora host is missing a security update.

Description

- Implement accurate fma (BZ#3268, #43358)

- Fix alignment of AVX save area on x86-64 (BZ#12113)

- Fix regex memory leaks (BZ#12078)

- Improve output of psiginfo (BZ#12107, BZ#12108)

- Don't return NULL address in getifaddrs (BZ#12093)

- Fix strstr and memmem algorithm (BZ#12092, #641124)

- Don't discard result of decoding ACE if AI_CANONIDN (#636642)

- Never expand $ORIGIN in privileged programs (#643306, CVE-2010-3847)

How to Run

Here is how to run the Fedora 14 : glibc-2.12.90-17 (2010-16308) as a standalone plugin via the Nessus web user interface (https://localhost:8834/):

Click to start a New Scan.
Select Advanced Scan.
Navigate to the Plugins tab.
On the top right corner click to Disable All plugins.
On the left side table select Fedora Local Security Checks plugin family.
On the right side table select Fedora 14 : glibc-2.12.90-17 (2010-16308) plugin ID 50036.
Specify the target on the Settings tab and click to Save the scan.
Run the scan.

Here are a few examples of how to run the plugin in the command line. Note that the examples below demonstrate the usage on the Linux / Unix platform.

Basic usage:

/opt/nessus/bin/nasl fedora_2010-16308.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a fedora_2010-16308.nasl -t <IP/HOST>

Run the plugin with trace script execution written to the console (useful for debugging):

/opt/nessus/bin/nasl -T - fedora_2010-16308.nasl -t <IP/HOST>

Run the plugin with using a state file for the target and updating it (useful for running multiple plugins on the target):

/opt/nessus/bin/nasl -K /tmp/state fedora_2010-16308.nasl -t <IP/HOST>

Go back to menu.
