FreeBSD : ruby -- Heap Overflow in Floating Point Parsing (cc9043cf-7f7a-426e-b2cc-8d1980618113)

medium Nessus Plugin ID 71072

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

Ruby developers report :

Any time a string is converted to a floating point value, a specially crafted string can cause a heap overflow. This can lead to a denial of service attack via segmentation faults and possibly arbitrary code execution. Any program that converts input of unknown origin to floating point values (especially common when accepting JSON) are vulnerable.

Solution

Update the affected packages.
