Vim helptags_one() function code execution
| vim-helptagsone-code-execution (35655) |  Medium Risk |
Description:
Vim could allow a remote attacker to execute arbitrary code on the system, caused by a format string vulnerability in the helptags_one() function. By persuading a victim to view a specially-crafted help file with a malicious helptags command, a remote attacker could exploit this vulnerability to execute arbitrary code on the system.
