man-db command line buffer overflow
|mandb-command-line-bo (12767)||Low Risk|
man-db is vulnerable to a buffer overflow, caused by insufficient bounds checking of the ult_src function. By supplying an overly long path as an argument, a remote attacker can overflow a buffer and cause a segmentation fault.
