"Description": "This update upgrades squid to version 4.10-alt1. \nSecurity Fix(es):\n\n * BDU:2020-01478: Уязвимость прокси-сервера Squid, существующая из-за недостаточной проверки входных данных, позволяющая нарушителю получить доступ к ограниченным HTTP-серверам\n\n * BDU:2020-01857: Уязвимость прокси-сервера Squid, связанная с записью за границами буфера, позволяющая нарушителю вызвать отказ в обслуживании\n\n * BDU:2020-01858: Уязвимость параметра append_domain прокси-сервера Squid, связанная с подделкой межсайтовых запросов, позволяющая нарушителю получить доступ к конфиденциальным данным и нарушить их целостность\n\n * BDU:2020-02596: Уязвимость прокси-сервера Squid, существующая из-за недостаточной проверки входных данных, позволяющая нарушителю раскрыть защищаемую информацию\n\n * BDU:2020-02597: Уязвимость прокси-сервера Squid, вызванная переполнением буфера, позволяющая нарушителю оказать воздействие на конфиденциальность, целостность и доступность защищаемой информации\n\n * BDU:2020-02598: Уязвимость прокси-сервера Squid, существующая из-за недостаточной проверки входных данных в ext_lm_group_acl, позволяющая нарушителю завершить процесс Squid и вызвать отказ в обслуживании для всех клиентов, использующих прокси\n\n * BDU:2020-05767: Уязвимость прокси-сервера Squid, связанная с выходом операции за границы буфера в памяти, позволяюшая нарушителю получить доступ к защищаемой информации\n\n * BDU:2021-01719: Уязвимость механизма HTTP дайджест-аутентификации прокси-сервера Squid, связанная с раскрытием информации, позволяющая нарушителю получить доступ к конфиденциальным данным\n\n * BDU:2021-01746: Уязвимость механизма обработки URN-ответов прокси-сервера Squid, связанная с недостатком механизма проверки размера копируемых данных, позволяющая нарушителю получить доступ к конфиденциальным данным, нарушить их целостность, а также вызвать отказ в обслуживании\n\n * BDU:2021-01748: Уязвимость заголовка запросов прокси-сервера Squid, связанная с недостатками обработки HTTP-запросов, позволяющая нарушителю оказать воздействие на целостность данных\n\n * BDU:2021-01750: Уязвимость программного пакета, который реализует функцию кэширующего прокси-сервера Squid, связанная с неверной нейтрализация особых элементов в выходных данных, позволяющая нарушителю оказать воздействие на целостность данных\n\n * CVE-2019-12523: An issue was discovered in Squid before 4.9. When handling a URN request, a corresponding HTTP request is made. This HTTP request doesn't go through the access checks that incoming HTTP requests go through. This causes all access checks to be bypassed and allows access to restricted HTTP servers, e.g., an attacker can connect to HTTP servers that only listen on localhost.\n\n * CVE-2019-12526: An issue was discovered in Squid before 4.9. URN response handling in Squid suffers from a heap-based buffer overflow. When receiving data from a remote server in response to an URN request, Squid fails to ensure that the response can fit within the buffer. This leads to attacker controlled data overflowing in the heap.\n\n * CVE-2019-12528: An issue was discovered in Squid before 4.10. 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.\n\n * CVE-2019-18676: An issue was discovered in Squid 3.x and 4.x through 4.8. Due to incorrect input validation, there is a heap-based buffer overflow that can result in Denial of Service to all clients using the proxy. Severity is high due to this vulnerability occurring before normal security checks; any remote client that can reach the proxy port can trivially perform the attack via a crafted URI scheme.\n\n * CVE-2019-18677: An issue was discovered in Squid 3.x and 4.x through 4.8 when the append_domain setting is used (because the appended characters do not properly interact with hostname length restrictions). Due to incorrect message processing, it can inappropriately redirect traffic to origins it should not be delivered to.\n\n * CVE-2019-18678: An issue was discovered in Squid 3.x and 4.x through 4.8. It allows attackers to smuggle HTTP requests through frontend software to a Squid instance that splits the HTTP Request pipeline differently. The resulting Response messages corrupt caches (between a client and Squid) with attacker-controlled content at arbitrary URLs. Effects are isolated to software between the attacker client and Squid. There are no effects on Squid itself, nor on any upstream servers. The issue is related to a request header containing whitespace between a header name and a colon.\n\n * CVE-2019-18679: An issue was discovered in Squid 2.x, 3.x, and 4.x through 4.8. Due to incorrect data management, it is vulnerable to information disclosure when processing HTTP Digest Authentication. Nonce tokens contain the raw byte value of a pointer that sits within heap memory allocation. This information reduces ASLR protections and may aid attackers isolating memory areas to target for remote code execution attacks.\n\n * CVE-2019-18860: Squid before 4.9, when certain web browsers are used, mishandles HTML in the host (aka hostname) parameter to cachemgr.cgi.\n\n * CVE-2020-8449: 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.\n\n * CVE-2020-8450: 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.\n\n * CVE-2020-8517: 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.",
