CVSS: 9.8EPSS: 13%CPEs: 13EXPL: 0CVE-2020-11945 – squid: improper access restriction upon Digest Authentication nonce replay could lead to remote code execution
https://notcve.org/view.php?id=CVE-2020-11945
An 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). Se detectó un problema en Squid versiones anteriores a 5.0.2. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00018.html http://master.squid-cache.org/Versions/v4/changesets/squid-4-eeebf0f37a72a2de08348e85ae34b02c34e9a811.patch http://www.openwall.com/lists/oss-security/2020/04/23/2 http://www.squid-cache.org/Versions/v4/changesets/squid-4-eeebf0f37a72a2de08348e85ae34b02c34e9a811.patch https://bugzilla.suse.com/show_bug.cgi?id=1170313 https://github.com/squid-cache/squid/commit/eeebf0f37a72a2de08348e85ae34b02c34e9a811 https://github.com/squid-cache/squid/pull/585 • CWE-190: Integer Overflow or Wraparound CWE-284: Improper Access Control •

https://notcve.org/view.php?id=CVE-2020-1983
A use after free vulnerability in ip_reass() in ip_input.c of libslirp 4.2.0 and prior releases allows crafted packets to cause a denial of service. Una vulnerabilidad de uso de la memoria previamente liberada en la función ip_reass() en el archivo ip_input.c de libslirp versiones 4.2.0 y anteriores permite que paquetes especialmente diseñados causen una denegación de servicio. A use-after-free flaw was found in the SLiRP networking implementation of the QEMU emulator. Specifically, this flaw occurs in the ip_reass() routine while reassembling incoming IP fragments whose combined size is bigger than 65k. This flaw allows an attacker to crash the QEMU process on the host, resulting in a denial of service. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00022.html http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00001.html https://gitlab.freedesktop.org/slirp/libslirp/-/commit/9ac0371bb8c0a40f5d9f82a1c25129660e81df04 https://gitlab.freedesktop.org/slirp/libslirp/-/issues/20 https://lists.debian.org/debian-lts-announce/2020/06/msg00032.html https://lists.debian.org/debian-lts-announce/2020/07/msg00020.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fe • CWE-416: Use After Free •
CVSS: 7.5EPSS: 0%CPEs: 16EXPL: 0CVE-2020-11008 – Malicious URLs can still cause Git to send a stored credential to the wrong server
https://notcve.org/view.php?id=CVE-2020-11008
Affected versions of Git have a vulnerability whereby Git can be tricked into sending private credentials to a host controlled by an attacker. This bug is similar to CVE-2020-5260(GHSA-qm7j-c969-7j4q). The fix for that bug still left the door open for an exploit where _some_ credential is leaked (but the attacker cannot control which one). Git uses external "credential helper" programs to store and retrieve passwords or other credentials from secure storage provided by the operating system. Specially-crafted URLs that are considered illegal as of the recently published Git versions can cause Git to send a "blank" pattern to helpers, missing hostname and protocol fields. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00003.html http://seclists.org/fulldisclosure/2020/May/41 https://github.com/git/git/commit/c44088ecc4b0722636e0a305f9608d3047197282 https://github.com/git/git/security/advisories/GHSA-hjc9-x69f-jqj7 https://github.com/git/git/security/advisories/GHSA-qm7j-c969-7j4q https://lists.debian.org/debian-lts-announce/2020/04/msg00015.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/74Q7WVJ6FKLIN62VS2JD2XCNW • CWE-20: Improper Input Validation CWE-522: Insufficiently Protected Credentials •
