https://notcve.org/view.php?id=CVE-2019-12520
15 Apr 2020 — An issue was discovered in Squid through 4.7 and 5. When receiving a request, Squid checks its cache to see if it can serve up a response. It does this by making a MD5 hash of the absolute URL of the request. If found, it servers the request. The absolute URL can include the decoded UserInfo (username and password) for certain protocols. • http://www.squid-cache.org/Versions/v4 • CWE-20: Improper Input Validation •

15 Apr 2020 — An issue was discovered in Squid through 4.7. When Squid is run as root, it spawns its child processes as a lesser user, by default the user nobody. This is done via the leave_suid call. leave_suid leaves the Saved UID as 0. This makes it trivial for an attacker who has compromised the child process to escalate their privileges back to root.

CVSS: 5.9EPSS: 7%CPEs: 10EXPL: 0CVE-2019-12521 – squid: Off-by-one error in addStackElement allows for heap buffer overflow and crash
https://notcve.org/view.php?id=CVE-2019-12521
15 Apr 2020 — An 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. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00018.html • CWE-122: Heap-based Buffer Overflow CWE-193: Off-by-one Error CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2019-12524
15 Apr 2020 — An issue was discovered in Squid through 4.7. When handling requests from users, Squid checks its rules to see if the request should be denied. Squid by default comes with rules to block access to the Cache Manager, which serves detailed server information meant for the maintainer. This rule is implemented via url_regex. The handler for url_regex rules URL decodes an incoming request. • https://gitlab.com/jeriko.one/security/-/blob/master/squid/CVEs/CVE-2019-12524.txt • CWE-20: Improper Input Validation CWE-306: Missing Authentication for Critical Function •

04 Feb 2020 — 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.

https://notcve.org/view.php?id=CVE-2019-12526
26 Nov 2019 — 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.
