Title:	Huawei EulerOS: Security Advisory for libevent (EulerOS-SA-2019-1439)
Summary:	The remote host is missing an update for the Huawei EulerOS 'libevent' package(s) announced via the EulerOS-SA-2019-1439 advisory.
Description:	Summary: The remote host is missing an update for the Huawei EulerOS 'libevent' package(s) announced via the EulerOS-SA-2019-1439 advisory. Vulnerability Insight: Multiple integer overflows in the evbuffer API in Libevent 1.4.x before 1.4.15, 2.0.x before 2.0.22, and 2.1.x before 2.1.5-beta allow context-dependent attackers to cause a denial of service or possibly have other unspecified impact via 'insanely large inputs' to the (1) evbuffer_add, (2) evbuffer_expand, or (3) bufferevent_write function, which triggers a heap-based buffer overflow or an infinite loop. NOTE: this identifier has been SPLIT per ADT3 due to different affected versions. See CVE-2015-6525 for the functions that are only affected in 2.0 and later.(CVE-2014-6272) An out of bounds read vulnerability was found in libevent in the search_make_new function. If an attacker could cause an application using libevent to attempt resolving an empty hostname, an out of bounds read could occur possibly leading to a crash.(CVE-2016-10197) A vulnerability was found in libevent with the parsing of DNS requests and replies. An attacker could send a forged DNS response to an application using libevent which could lead to reading data out of bounds on the heap, potentially disclosing a small amount of application memory.(CVE-2016-10195) A vulnerability was found in libevent with the parsing of IPv6 addresses. If an attacker could cause an application using libevent to parse a malformed address in IPv6 notation of more than 2GiB in length, a stack overflow would occur leading to a crash.(CVE-2016-10196) Affected Software/OS: 'libevent' package(s) on Huawei EulerOS Virtualization 3.0.1.0. Solution: Please install the updated package(s). CVSS Score: 7.5 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:P/A:P
