17 Mar 2023 — ssh-add in OpenSSH before 9.3 adds smartcard keys to ssh-agent without the intended per-hop destination constraints. The earliest affected version is 8.9. Fabian Bäumer, Marcus Brinkmann, Joerg Schwenk discovered that the SSH protocol was vulnerable to a prefix truncation attack. If a remote attacker was able to intercept SSH communications, extension negotiation messages could be truncated, possibly leading to certain algorithms and features being downgraded. This issue is known as the Terrapin attack. • https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/AN2UDTXEUSKFIOIYMV6JNI5VSBMYZOFT •

09 Nov 2022 — An issue was discovered in Python before 3.11.1. An unnecessary quadratic algorithm exists in one path when processing some inputs to the IDNA (RFC 3490) decoder, such that a crafted, unreasonably long name being presented to the decoder could lead to a CPU denial of service. Hostnames are often supplied by remote servers that could be controlled by a malicious actor; in such a scenario, they could trigger excessive CPU consumption on the client attempting to make use of an attacker-supplied supposed hostna... • https://github.com/python/cpython/issues/98433 • CWE-400: Uncontrolled Resource Consumption CWE-407: Inefficient Algorithmic Complexity •

05 Aug 2022 — A NULL pointer dereference flaw was found in GnuTLS. As Nettle's hash update functions internally call memcpy, providing zero-length input may cause undefined behavior. This flaw leads to a denial of service after authentication in rare circumstances. Se ha encontrado un fallo de desreferencia de puntero NULL en GnuTLS. Como las funciones de actualización de hash de Nettle llaman internamente a memcpy, proporcionar una entrada de longitud cero puede causar un comportamiento indefinido. • https://access.redhat.com/security/cve/CVE-2021-4209 • CWE-476: NULL Pointer Dereference •

28 Jun 2022 — curl < 7.84.0 supports "chained" HTTP compression algorithms, meaning that a serverresponse can be compressed multiple times and potentially with different algorithms. The number of acceptable "links" in this "decompression chain" was unbounded, allowing a malicious server to insert a virtually unlimited number of compression steps.The use of such a decompression chain could result in a "malloc bomb", makingcurl end up spending enormous amounts of allocated heap memory, or trying toand returning out of memo... • https://github.com/HimanshuS67/external_curl_AOSP10_CVE-2022-32206 • CWE-770: Allocation of Resources Without Limits or Throttling •

28 Jun 2022 — When curl < 7.84.0 saves cookies, alt-svc and hsts data to local files, it makes the operation atomic by finalizing the operation with a rename from a temporary name to the final target file name.In that rename operation, it might accidentally *widen* the permissions for the target file, leaving the updated file accessible to more users than intended.

01 Jun 2022 — Using its HSTS support, curl can be instructed to use HTTPS directly insteadof using an insecure clear-text HTTP step even when HTTP is provided in theURL. This mechanism could be bypassed if the host name in the given URL used atrailing dot while not using one when it built the HSTS cache.
