innfeed -c flag buffer overflow
| innfeed-c-bo (6398) |  High Risk |
Description:
Innfeed is vulnerable to a buffer overflow when using the -c flag. Due to insufficient bounds checking in the logorprint function, a local attacker can overflow a buffer to gain elevated privileges, such as uid (news) or gid (news). A local attacker could exploit this vulnerability to gain root privileges because startinnfeed is installed suid root.
