CVSS: 7.5EPSS: 0%CPEs: 62EXPL: 1CVE-2020-8285 – curl: Malicious FTP server can trigger stack overflow when CURLOPT_CHUNK_BGN_FUNCTION is used
https://notcve.org/view.php?id=CVE-2020-8285
curl 7.21.0 to and including 7.73.0 is vulnerable to uncontrolled recursion due to a stack overflow issue in FTP wildcard match parsing. curl versiones 7.21.0 hasta 7.73.0 e incluyéndola, es vulnerable a una recursividad no controlada debido a un problema de desbordamiento de la pila en el análisis de coincidencias del comodín FTP Libcurl offers a wildcard matching functionality, which allows a callback (set with `CURLOPT_CHUNK_BGN_FUNCTION`) to return information back to libcurl on how to handle a specific entry in a directory when libcurl iterates over a list of all available entries. When this callback returns `CURL_CHUNK_BGN_FUNC_SKIP`, to tell libcurl to not deal with that file, the internal function in libcurl then calls itself recursively to handle the next directory entry. If there's a sufficient amount of file entries and if the callback returns "skip" enough number of times, libcurl runs out of stack space. The exact amount will of course vary with platforms, compilers and other environmental factors. • http://seclists.org/fulldisclosure/2021/Apr/51 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://curl.se/docs/CVE-2020-8285.html https://github.com/curl/curl/issues/6255 https://hackerone.com/reports/1045844 https://lists.apache.org/thread.html/r58af02e294bd07f487e2c64ffc0a29b837db5600e33b6e698b9d696b%40%3Cissues.bookkeeper.apache.org%3E https://lists.apache.org/thread.html/rf4c02775860db415b4955778a131c2795223f61cb8c6a450893651e4%40%3Cissues.bookkeeper.apache.org%3E https://lists.debian.org/debian-lts • CWE-121: Stack-based Buffer Overflow CWE-674: Uncontrolled Recursion CWE-787: Out-of-bounds Write •

CVSS: 4.3EPSS: 0%CPEs: 40EXPL: 0CVE-2020-1968 – Raccoon attack
https://notcve.org/view.php?id=CVE-2020-1968
The Raccoon attack exploits a flaw in the TLS specification which can lead to an attacker being able to compute the pre-master secret in connections which have used a Diffie-Hellman (DH) based ciphersuite. In such a case this would result in the attacker being able to eavesdrop on all encrypted communications sent over that TLS connection. The attack can only be exploited if an implementation re-uses a DH secret across multiple TLS connections. Note that this issue only impacts DH ciphersuites and not ECDH ciphersuites. This issue affects OpenSSL 1.0.2 which is out of support and no longer receiving public updates. • https://lists.debian.org/debian-lts-announce/2020/09/msg00016.html https://security.gentoo.org/glsa/202210-02 https://security.netapp.com/advisory/ntap-20200911-0004 https://usn.ubuntu.com/4504-1 https://www.openssl.org/news/secadv/20200909.txt https://www.oracle.com//security-alerts/cpujul2021.html https://www.oracle.com/security-alerts/cpuApr2021.html https://www.oracle.com/security-alerts/cpuapr2022.html https://www.oracle.com/security-alerts/cpujan2021.html https://www.o • CWE-203: Observable Discrepancy •

https://notcve.org/view.php?id=CVE-2020-8177
curl 7.20.0 through 7.70.0 is vulnerable to improper restriction of names for files and other resources that can lead too overwriting a local file when the -J flag is used. curl versiones 7.20.0 hasta 7.70.0, es vulnerable a una restricción inapropiada de nombres para archivos y otros recursos que pueden conllevar a sobrescribir demasiado un archivo local cuando el flag -J es usado A flaw was found in curl. Overwriting local files is possible when using a certain combination of command line options. Requesting content from a malicious server could lead to overwriting local files with compromised files leading to unknown effects. The highest threat from this vulnerability is to file integrity. • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://curl.se/docs/CVE-2020-8177.html https://hackerone.com/reports/887462 https://www.debian.org/security/2021/dsa-4881 https://www.oracle.com/security-alerts/cpujan2022.html https://access.redhat.com/security/cve/CVE-2020-8177 https://bugzilla.redhat.com/show_bug.cgi?id=1847915 • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') CWE-99: Improper Control of Resource Identifiers ('Resource Injection') •

https://notcve.org/view.php?id=CVE-2020-13817
ntpd in ntp before 4.2.8p14 and 4.3.x before 4.3.100 allows remote attackers to cause a denial of service (daemon exit or system time change) by predicting transmit timestamps for use in spoofed packets. The victim must be relying on unauthenticated IPv4 time sources. There must be an off-path attacker who can query time from the victim's ntpd instance. ntpd en ntp versiones anteriores a 4.2.8p14 y versiones 4.3.x versiones anteriores a 4.3.100, permite a atacantes remotos causar una denegación de servicio (salida del demonio o cambio de hora del sistema) mediante la predicción de las marcas de tiempo de transmisión para su uso en paquetes falsificados. La víctima debe confiar en fuentes de tiempo IPv4 no autenticadas. Debe haber un atacante fuera de la ruta que pueda consultar el tiempo desde la instancia ntpd de la víctima A high-performance ntpd instance that gets its time from unauthenticated IPv4 time sources may be vulnerable to an off-path attacker who can query time from the victim's ntpd instance. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00044.html http://support.ntp.org/bin/view/Main/NtpBug3596 https://bugs.ntp.org/show_bug.cgi?id=3596 https://security.gentoo.org/glsa/202007-12 https://security.netapp.com/advisory/ntap-20200625-0004 https://www.oracle.com/security-alerts/cpujan2022.html https://access.redhat.com/security/cve/CVE-2020-13817 https://bugzilla.redhat.com/show_bug& • CWE-330: Use of Insufficiently Random Values CWE-358: Improperly Implemented Security Check for Standard •
