CVE-2020-25866
https://notcve.org/view.php?id=CVE-2020-25866
In Wireshark 3.2.0 to 3.2.6 and 3.0.0 to 3.0.13, the BLIP protocol dissector has a NULL pointer dereference because a buffer was sized for compressed (not uncompressed) messages. This was addressed in epan/dissectors/packet-blip.c by allowing reasonable compression ratios and rejecting ZIP bombs. En Wireshark versiones 3.2.0 hasta 3.2.6 y versiones 3.0.0 hasta 3.0.13, el disector del protocolo BLIP presenta una desreferencia del puntero NULL porque un búfer fue dimensionado para mensajes comprimidos (no sin comprimir). Esto fue abordado en el archivo epan/disactors/packet-blip.c permitiendo relaciones de compresión razonables y rechazando las bombas ZIP • http://lists.opensuse.org/opensuse-security-announce/2020-11/msg00035.html http://lists.opensuse.org/opensuse-security-announce/2020-11/msg00038.html https://gitlab.com/wireshark/wireshark/-/commit/4a948427100b6c109f4ec7b4361f0d2aec5e5c3f https://gitlab.com/wireshark/wireshark/-/issues/16866 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4DQHPKZFQ7W3X34RYN3FWFYCFJD4FXJW https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6IGRYKW4XLR44YDWTAH547ODYYBYPB2D • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2020-25862
In Wireshark 3.2.0 to 3.2.6, 3.0.0 to 3.0.13, and 2.6.0 to 2.6.20, the TCP dissector could crash. This was addressed in epan/dissectors/packet-tcp.c by changing the handling of the invalid 0xFFFF checksum. En Wireshark versiones 3.2.0 hasta 3.2.6, versiones 3.0.0 hasta 3.0.13 y versiones 2.6.0 hasta 2.6.20, el disector TCP podría bloquearse. Esto fue abordado en el archivo epan/disactors/packet-tcp.c mediante el cambio en el manejo del checksum 0xFFFF no válido • http://lists.opensuse.org/opensuse-security-announce/2020-11/msg00035.html http://lists.opensuse.org/opensuse-security-announce/2020-11/msg00038.html https://gitlab.com/wireshark/wireshark/-/commit/7f3fe6164a68b76d9988c4253b24d43f498f1753 https://gitlab.com/wireshark/wireshark/-/issues/16816 https://lists.debian.org/debian-lts-announce/2021/02/msg00008.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4DQHPKZFQ7W3X34RYN3FWFYCFJD4FXJW https://lists.fedoraproject.org/archives • CWE-354: Improper Validation of Integrity Check Value •
CVE-2020-7070 – PHP parses encoded cookie names so malicious `__Host-` cookies can be sent
https://notcve.org/view.php?id=CVE-2020-7070
In PHP versions 7.2.x below 7.2.34, 7.3.x below 7.3.23 and 7.4.x below 7.4.11, when PHP is processing incoming HTTP cookie values, the cookie names are url-decoded. This may lead to cookies with prefixes like __Host confused with cookies that decode to such prefix, thus leading to an attacker being able to forge cookie which is supposed to be secure. See also CVE-2020-8184 for more information. En PHP versiones 7.2.x por debajo de 7.2.34, versiones 7.3.x por debajo de 7.3.23 y versiones 7.4.x por debajo de 7.4.11, cuando PHP procesa valores de cookies HTTP entrantes, los nombres de las cookies se decodifican de la URL. Esto puede conllevar a que las cookies con prefijos como __Host se confundan con las cookies que decodifican dicho prefijo, lo que conlleva a que un atacante pueda falsificar una cookie que se supone que es segura. • http://cve.circl.lu/cve/CVE-2020-8184 http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00045.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00067.html https://bugs.php.net/bug.php?id=79699 https://hackerone.com/reports/895727 https://lists.debian.org/debian-lts-announce/2020/10/msg00008.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/7EVDN7D3IB4EAI4D3ZOM2OJKQ5SD7K4E https://lists.fedoraproject.org/archives/list/ • CWE-20: Improper Input Validation CWE-565: Reliance on Cookies without Validation and Integrity Checking •
CVE-2020-7069 – Wrong ciphertext/tag in AES-CCM encryption for a 12 bytes IV
https://notcve.org/view.php?id=CVE-2020-7069
In PHP versions 7.2.x below 7.2.34, 7.3.x below 7.3.23 and 7.4.x below 7.4.11, when AES-CCM mode is used with openssl_encrypt() function with 12 bytes IV, only first 7 bytes of the IV is actually used. This can lead to both decreased security and incorrect encryption data. En PHP versiones 7.2.x por debajo de 7.2.34, versiones 7.3.x por debajo de 7.3.23 y versiones 7.4.x por debajo de 7.4.11, cuando el modo AES-CCM es usado con la función openssl_encrypt() con 12 bytes IV, solo los primeros 7 bytes del IV está actualmente usado. Esto puede conllevar a una disminución de seguridad y datos de cifrado incorrectos • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00045.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00067.html https://bugs.php.net/bug.php?id=79601 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/7EVDN7D3IB4EAI4D3ZOM2OJKQ5SD7K4E https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/P2J3ZZDHCSX65T5QWV4AHBN7MOJXBEKG https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/R • CWE-20: Improper Input Validation CWE-326: Inadequate Encryption Strength •
CVE-2020-11979 – ant: insecure temporary file
https://notcve.org/view.php?id=CVE-2020-11979
As mitigation for CVE-2020-1945 Apache Ant 1.10.8 changed the permissions of temporary files it created so that only the current user was allowed to access them. Unfortunately the fixcrlf task deleted the temporary file and created a new one without said protection, effectively nullifying the effort. This would still allow an attacker to inject modified source files into the build process. Como mitigación para CVE-2020-1945, Apache Ant versión 1.10.8, cambió los permisos de los archivos temporales que creó para que solo el usuario actual pudiera acceder a ellos. Desafortunadamente, la tarea fixcrlf eliminó el archivo temporal y creó uno nuevo sin dicha protección, anulando efectivamente el esfuerzo. • https://github.com/gradle/gradle/security/advisories/GHSA-j45w-qrgf-25vm https://lists.apache.org/thread.html/r107ea1b1a7a214bc72fe1a04207546ccef542146ae22952e1013b5cc%40%3Cdev.creadur.apache.org%3E https://lists.apache.org/thread.html/r1dc8518dc99c42ecca5ff82d0d2de64cd5d3a4fa691eb9ee0304781e%40%3Cdev.creadur.apache.org%3E https://lists.apache.org/thread.html/r2306b67f20c24942b872b0a41fbdc9330e8467388158bcd19c1094e0%40%3Cdev.creadur.apache.org%3E https://lists.apache.org/thread.html/r4ca33fad3fb39d130cda287d5a60727d9e706e6f2cf2339b95729490%40%3Cdev.creadur.apache.org%3E https • CWE-377: Insecure Temporary File CWE-379: Creation of Temporary File in Directory with Insecure Permissions •
