Description
According to the versions of the squid package installed, the EulerOS
installation on the remote host is affected by the following
vulnerabilities :
An issue was discovered in Squid before 4.10. Due to
incorrect input validation, it can interpret crafted
HTTP requests in unexpected ways to access server
resources prohibited by earlier security
filters.(CVE-2020-8449)
An issue was discovered in Squid before 4.10. Due to
incorrect buffer management, a remote client can cause
a buffer overflow in a Squid instance acting as a
reverse proxy.(CVE-2020-8450)
An issue was discovered in Squid before 4.10. Due to
incorrect input validation, the NTLM authentication
credentials parser in ext_lm_group_acl may write to
memory outside the credentials buffer. On systems with
memory access protections, this can result in the
helper process being terminated unexpectedly. This
leads to the Squid process also terminating and a
denial of service for all clients using the
proxy.(CVE-2020-8517)
Note that Tenable Network Security has extracted the preceding
description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

It allows a crafted FTP server to trigger disclosure of sensitive information from heap memory, such as information associated with other users' sessions or non-Squid processes.(CVE-2019-12528)\n\nAn issue was discovered in Squid before 4.10. Due to incorrect input validation, it can interpret crafted HTTP requests in unexpected ways to access server resources prohibited by earlier security filters.(CVE-2020-8449)\n\nAn issue was discovered in Squid before 4.10. Due to incorrect buffer management, a remote client can cause a buffer overflow in a Squid instance acting as a reverse proxy.(CVE-2020-8450)\n\nAn issue was discovered in Squid before 4.10. Due to incorrect input validation, the NTLM authentication credentials parser in ext_lm_group_acl may write to memory outside the credentials buffer. On systems with memory access protections, this can result in the helper process being terminated unexpectedly. This leads to the Squid process also terminating and a denial of service for all clients using the proxy.(CVE-2020-8517)\n\nAn issue was discovered in Squid through 4.7. When handling the tag esi:when when ESI is enabled, Squid calls ESIExpression::Evaluate. This function uses a fixed stack buffer to hold the expression while it's being evaluated. When processing the expression, it could either evaluate the top of the stack, or add a new member to the stack. When adding a new member, there is no check to ensure that the stack won't overflow.(CVE-2019-12519)\n\nAn issue was discovered in Squid through 4.7. When Squid is parsing ESI, it keeps the ESI elements in ESIContext. ESIContext contains a buffer for holding a stack of ESIElements. When a new ESIElement is parsed, it is added via addStackElement. addStackElement has a check for the number of elements in this buffer, but it's off by 1, leading to a Heap Overflow of 1 element. The overflow is within the same structure so it can't affect adjacent memory blocks, and thus just leads to a crash while processing.(CVE-2019-12521)\n\nAn issue was discovered in Squid before 5.0.2. A remote attacker can replay a sniffed Digest Authentication nonce to gain access to resources that are otherwise forbidden. This occurs because the attacker can overflow the nonce reference counter (a short integer). Remote code execution may occur if the pooled token credentials are freed (instead of replayed as valid credentials).(CVE-2020-11945)\");\n\n script_tag(name:\"affected\", value:\"'squid' package(s) on Huawei EulerOS V2.0SP2.\");\n\n script_tag(name:\"solution\", value:\"Please install the updated package(s).\");\n\n script_tag(name:\"solution_type\", value:\"VendorFix\");\n script_tag(name:\"qod_type\", value:\"package\");\n\n exit(0);\n}\n\ninclude(\"revisions-lib.inc\");\ninclude(\"pkg-lib-rpm.inc\");\n\nrelease = rpm_get_ssh_release();\nif(!release)\n exit(0);\n\nres = \"\";\nreport = \"\";\n\nif(release == \"EULEROS-2.0SP2\") {\n\n if(!isnull(res = isrpmvuln(pkg:\"squid\", rpm:\"squid~3.5.20~2.2.h7\", rls:\"EULEROS-2.0SP2\"))) {\n report += res;\n }\n\n if(!isnull(res = isrpmvuln(pkg:\"squid-migration-script\", rpm:\"squid-migration-script~3.5.20~2.2.h7\", rls:\"EULEROS-2.0SP2\"))) {\n report += res;\n }\n\n if(report != \"\") {\n security_message(data:report);\n } else if (__pkg_match) {\n exit(99);\n }\n exit(0);\n}\n\nexit(0);", "cvss": {"score": 7.5, "vector": "AV:N/AC:L/Au:N/C:P/I:P/A:P"}}, {"lastseen": "2020-05-22T13:26:39", "bulletinFamily": "scanner", "cvelist": ["CVE-2019-12528", "CVE-2020-8450", "CVE-2020-11945", "CVE-2020-8449"], "description": "The remote host is missing an update for the ", "modified": "2020-05-20T00:00:00", "published": "2020-05-18T00:00:00", "id": "OPENVAS:1361412562310877853", "href": "http://plugins.openvas.org/nasl.php?oid=1361412562310877853", "type": "openvas", "title": "Fedora: Security Advisory for squid (FEDORA-2020-56e809930e)", "sourceData": "# Copyright (C) 2020 Greenbone Networks GmbH\n# Some text descriptions might be excerpted from (a) referenced\n# source(s), and are Copyright (C) by the respective right holder(s).\n#\n# SPDX-License-Identifier: GPL-2.0-or-later\n#\n# This program is free software; you can redistribute it and/or\n# modify it under the terms of the GNU General Public License\n# as published by the Free Software Foundation; either version 2\n# of the License, or (at your option) any later version.\n#\n# This program is distributed in the hope that it will be useful,\n# but WITHOUT ANY WARRANTY; without even the implied warranty of\n# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
