hopper-vul	9903253c34	Add str len check in config_sortlist to avoid stack overflow (#497 ) In ares_set_sortlist, it calls config_sortlist(..., sortstr) to parse the input str and initialize a sortlist configuration. However, ares_set_sortlist has not any checks about the validity of the input str. It is very easy to create an arbitrary length stack overflow with the unchecked `memcpy(ipbuf, str, q-str);` and `memcpy(ipbufpfx, str, q-str);` statements in the config_sortlist call, which could potentially cause severe security impact in practical programs. This commit add necessary check for `ipbuf` and `ipbufpfx` which avoid the potential stack overflows. fixes #496 Fix By: @hopper-vul	2 years ago
Manish Mehra	810c2322f9	Configurable hosts path for file_lookup (#465 ) This changeset adds support for configurable hosts file ARES_OPT_HOSTS_FILE (similar to ARES_OPT_RESOLVCONF). Co-authored-by: Manish Mehra (@mmehra)	3 years ago
Fionn Fitzmaurice	6d6cd5daf6	Avoid buffer overflow in RC4 loop comparison (#336 ) The rc4 function iterates over a buffer of size buffer_len who's maximum value is INT_MAX with a counter of type short that is not guaranteed to have maximum size INT_MAX. In circumstances where short is narrower than int and where buffer_len is larger than the maximum value of a short, it may be possible to loop infinitely as counter will overflow and never be greater than or equal to buffer_len. The solution is to make the comparison be between types of equal width. This commit defines counter as an int. Fix By: Fionn Fitzmaurice (@fionn)	5 years ago
