Vilistextum: Buffer overflow vulnerability — GLSA 200501-10

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

Affected packages

Package 	app-text/vilistextum on all architectures

Description

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

Impact

Workaround

There is no known workaround at this time.

Resolution

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