CVSS: 7.5EPSS: 19%CPEs: 18EXPL: 0CVE-2019-18679 – squid: Information Disclosure issue in HTTP Digest Authentication
https://notcve.org/view.php?id=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. Se descubrió un problema en Squid versiones 2.x, 3.x y versiones 4.x hasta 4.8. • http://www.squid-cache.org/Advisories/SQUID-2019_11.txt http://www.squid-cache.org/Versions/v4/changesets/squid-4-671ba97abe929156dc4c717ee52ad22fba0f7443.patch https://bugzilla.suse.com/show_bug.cgi?id=1156324 https://github.com/squid-cache/squid/pull/491 https://lists.debian.org/debian-lts-announce/2019/12/msg00011.html https://lists.debian.org/debian-lts-announce/2020/07/msg00009.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MTM74TU2BSLT5B3H4F3UDW5367 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2019-12854
Due to incorrect string termination, Squid cachemgr.cgi 4.0 through 4.7 may access unallocated memory. On systems with memory access protections, this can cause the CGI process to terminate unexpectedly, resulting in a denial of service for all clients using it. Debido a una terminación de cadena incorrecta, el archivo cachemgr.cgi de Squid versiones 4.0 hasta 4.7 puede acceder a la memoria no asignada. En sistemas con protecciones de acceso a memoria, esto puede causar que el proceso CGI finalice inesperadamente, resultando en una denegación de servicio para todos los clientes que lo usan. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00053.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00056.html http://www.squid-cache.org/Advisories/SQUID-2019_1.txt http://www.squid-cache.org/Versions/v4/changesets/squid-4-2981a957716c61ff7e21eee1d7d6eb5a237e466d.patch https://bugs.squid-cache.org/show_bug.cgi?id=4937 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/SPXN2CLAGN5QSQBTOV5IGVLDOQSRFNTZ https://seclists.org/bugtraq/2019&#x • CWE-400: Uncontrolled Resource Consumption •
CVSS: 5.9EPSS: 1%CPEs: 22EXPL: 0CVE-2019-12529 – squid: Out of bounds read in Proxy-Authorization header causes DoS
https://notcve.org/view.php?id=CVE-2019-12529
An issue was discovered in Squid 2.x through 2.7.STABLE9, 3.x through 3.5.28, and 4.x through 4.7. When Squid is configured to use Basic Authentication, the Proxy-Authorization header is parsed via uudecode. uudecode determines how many bytes will be decoded by iterating over the input and checking its table. The length is then used to start decoding the string. There are no checks to ensure that the length it calculates isn't greater than the input buffer. This leads to adjacent memory being decoded as well. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00053.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00056.html http://www.squid-cache.org/Versions/v4/changesets http://www.squid-cache.org/Versions/v4/changesets/squid-4-dd46b5417809647f561d8a5e0e74c3aacd235258.patch https://github.com/squid-cache/squid/commits/v4 https://lists.debian.org/debian-lts-announce/2019/07/msg00018.html https://lists.debian.org/debian-lts-announce/2020/07/msg00009.html https://lists • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2019-12525
An issue was discovered in Squid 3.3.9 through 3.5.28 and 4.x through 4.7. When Squid is configured to use Digest authentication, it parses the header Proxy-Authorization. It searches for certain tokens such as domain, uri, and qop. Squid checks if this token's value starts with a quote and ends with one. If so, it performs a memcpy of its length minus 2. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00053.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00056.html http://www.squid-cache.org/Versions/v4/changesets http://www.squid-cache.org/Versions/v4/changesets/squid-4-7f73e9c5d17664b882ed32590e6af310c247f320.patch https://github.com/squid-cache/squid/commits/v4 https://lists.debian.org/debian-lts-announce/2019/07/msg00018.html https://lists.debian.org/debian-lts-announce/2020/07/msg00009.html https://lists • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •
