Vilistextum is vulnerable to a buffer overflow that allows an attacker to execute arbitrary code through the use of a malicious webpage.

2.  Impact Information


Vilistextum is an HTML to text converter.


Ariel Berkman discovered that Vilistextum unsafely reads data into an array without checking the length. This code vulnerability may lead to a buffer overflow.


A remote attacker could craft a malicious webpage which, when converted, would result in the execution of arbitrary code with the rights of the user running Vilistextum.

3.  Resolution Information


There is no known workaround at this time.


All Vilistextum users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/vilistextum-2.6.7"
