For a full description of the bug, see


Here is a short extract from that page:

"GNU gv is prone to a stack-based buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized memory buffer.

Exploiting this issue allows attackers to execute arbitrary machine code in the context of users running the affected application. Failed attempts will likely crash the application, resulting in denial-of-service conditions.

Version 3.6.2 is reported vulnerable; other versions may also be affected.

NOTE: Various other applications may employ embedded GNU gv code and could also be vulnerable as a result."
