Categoría:	Huawei EulerOS Local Security Checks
Título:	Huawei EulerOS: Security Advisory for haproxy (EulerOS-SA-2019-1650)
Resumen:	The remote host is missing an update for the Huawei EulerOS 'haproxy' package(s) announced via the EulerOS-SA-2019-1650 advisory.
Descripción:	Summary: The remote host is missing an update for the Huawei EulerOS 'haproxy' package(s) announced via the EulerOS-SA-2019-1650 advisory. Vulnerability Insight: An out-of-bounds read issue was discovered in the HTTP/2 protocol decoder in HAProxy 1.8.x and 1.9.x through 1.9.0 which can result in a crash. The processing of the PRIORITY flag in a HEADERS frame requires 5 extra bytes, and while these bytes are skipped, the total frame length was not re-checked to make sure they were present in the frame.(CVE-2018-20615) An issue was discovered in dns.c in HAProxy through 1.8.14. In the case of a compressed pointer, a crafted packet can trigger infinite recursion by making the pointer point to itself, or create a long chain of valid pointers resulting in stack exhaustion.(CVE-2018-20103) An out-of-bounds read in dns_validate_dns_response in dns.c was discovered in HAProxy through 1.8.14. Due to a missing check when validating DNS responses, remote attackers might be able read the 16 bytes corresponding to an AAAA record from the non-initialized part of the buffer, possibly accessing anything that was left on the stack, or even past the end of the 8193-byte buffer, depending on the value of accepted_payload_size.(CVE-2018-20102) Affected Software/OS: 'haproxy' package(s) on Huawei EulerOS V2.0SP8. Solution: Please install the updated package(s). CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:N/A:N
