12e0d889 | 2018-10-28 16:46:24 | Convert evbuffer_strspn() (internal helper) to use size_t As pointed by @yankeehacker in #590: Signed to Unsigned Conversion Error - buffer.c:1623 Description: This assignment creates a type mismatch by populating an unsigned variable with a signed value. The signed integer will be implicitly cast to an unsigned integer, converting negative values into positive ones. If an attacker can control the signed value, it may be possible to trigger a buffer overflow if the value specifies the length of a memory write. Remediation: Do not rely on implicit casts between signed and unsigned values because the result can take on an unexpected value and violate weak assumptions made elsewhere in the program. Fixes: #590 (cherry picked from commit 931ec2370228e40309af51b86e10fa364a37a20e) | |

cdd52e7f | 2018-05-23 15:39:13 | Fix missing LIST_HEAD Despite the presence of 'sys/queue.h' in some stdlib implementations (i.e. uclibc) 'LIST_HEAD' macro can be missing. This fix defines this macro in the same manner as was done previously for 'TAILQ_'. Fixes: #539 Closes: #639 (cherry-picked) Backport: 2.1.9 (cherry picked from commit 95918754d2ba7e6bffe0fc74bebed60bd917c10c) | |

d6326104 | 2018-04-20 15:48:32 | Fix assert() condition in evbuffer_drain() for IOCP In the case of iocp, in the for loop above, there is a situation where: remaining == chain->off == 0 And this happens due to CHAIN_PINNED_R() case (that is used only in buffer_iocp.c) Closes: #630 (picked) (cherry picked from commit ab3224c3e66cf92779f8bd91ffe90445e636fa50) | |

9f4d0dce | 2017-08-14 23:03:48 | Fix wrong assert in evbuffer_drain() "chain" cannot be NULL here because we have at least one chain (we handle empty buffer separatelly) and hence loop will be executed at least once.
