2019-05-03Fixed endless loop/ OOB write on 64 bit systems with large buffers.tobias1-3/+3
If a buffer exceeds UINT_MAX (which is only possible on 64 bit systems) an endless loop or OOB write can occur in buffer-specific readline functions. Switching variables in function scope to size_t solves these issue because relevant fields in struct buffer are already size_t. ok cheloha, deraadt, nicm, tedu

2015-01-05Fix CVE-2014-6272 in Libevent 1.4 from upstream:bluhm1-9/+23
- https://github.com/libevent/libevent/commit/7b21c4eabf1f3946d3f63cce1319c490caab8ecf - For this fix, we need to make sure that passing too-large inputs to the evbuffer functions can't make us do bad things with the heap. On top of that do: - Update libevent version to 1.4.15-stable. - Use SIZE_MAX from limits.h instead of a private define. - Do not declare 'size_t need' twice to avoid a compiler warning. OK sthen
2014-11-21libraries shouldnt print to stderr when things dont go their way.dlg1-3/+3
switch fprintf(stderr) over to event_warn() on malloc failure. fix up an errant newline in an existing event_warn while there. originally i just wanted to delete the fprintf diff from nicm@ who is away from a keyboard right now so cant commit guenther@ agrees with the idea

2010-07-12Update to 1.4.14b.nicm1-3/+5
From their change log: o Fix memory-leak of signal handler array with kqueue. [backport] o Make evutil_make_socket_nonblocking() leave any other flags alone. o Adjusted fcntl() retval comparison on evutil_make_socket_nonblocking(). o Re-add event_siglcb; some old code _was_ still using it. :( o Fix a free(NULL) in min_heap.h o Clean up properly when adding a signal handler fails. Also a local change to use an int rather than a long for fcntl(). ok guenther deraadt
2010-04-21Update libevent to 1.4.13.nicm1-38/+112
This is the core library only, the DNS parts are removed and it does not include the other extra bits (HTTP, DNS, and RPC), a separate port for these will appear in due course. Thanks to jsg, sthen, alek, gilles, jacekm, bernd and any others I've forgotten for testing/comments. Note that /usr/include/evdns.h should be removed after updating. ok deraadt

2006-03-18- limit the amount of data bufferevents are going to consume to somethingbrad1-3/+18
reasonable; in some circumstances it could happen that libevent happily allocated 100MB in read buffers without telling the user; found by christopher maxwell - parts of these changes are from his patch. - allow setting an event base for bufferevents; from phil oleson - improved manpage from Phil Oleson From libevent CVS
