A denial of service via regular expression in the py.path.svnwc component of py (aka python-py) through 1.9.0 could be used by attackers to cause a compute-time denial of service attack by supplying malicious input to the blame functionality. Una denegación de servicio por medio de una expresión regular en el componente py.path.svnwc de py (también se conoce como python-py) versiones hasta 1.9.0, podría ser usada por atacantes para causar un ataque de denegación de servicio del compute-time al suministrar una entrada maliciosa en la funcionalidad blame • https://github.com/pytest-dev/py/issues/256 https://github.com/pytest-dev/py/pull/257 https://github.com/pytest-dev/py/pull/257/commits/4a9017dc6199d2a564b6e4b0aa39d6d8870e4144 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/AYWNYEV3FGDHPIHX4DDUDMFZ6NLCQRC4 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CHDTINIBJZ67T3W74QTBIY5LPKAXEOGR https://www.oracle.com/security-alerts/cpujul2022.html •
CVSS: 6.1EPSS: 0%CPEs: 10EXPL: 2CVE-2020-27783 – python-lxml: mXSS due to the use of improper parser
https://notcve.org/view.php?id=CVE-2020-27783
A XSS vulnerability was discovered in python-lxml's clean module. The module's parser didn't properly imitate browsers, which caused different behaviors between the sanitizer and the user's page. A remote attacker could exploit this flaw to run arbitrary HTML/JS code. Se detectó una vulnerabilidad de tipo XSS en el módulo de limpieza de python-lxml. El analizador del módulo no imitaba apropiadamente los navegadores, lo que causaba comportamientos diferentes entre el sanitizador y la página del usuario. • https://advisory.checkmarx.net/advisory/CX-2020-4286 https://bugzilla.redhat.com/show_bug.cgi?id=1901633 https://lists.debian.org/debian-lts-announce/2020/12/msg00028.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JKG67GPGTV23KADT4D4GK4RMHSO4CIQL https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TMHVKRUT22LVWNL3TB7HPSDHJT74Q3JK https://security.netapp.com/advisory/ntap-20210521-0003 https://www.debian.org/security/2020/dsa-481 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

In Wireshark through 3.2.7, the Facebook Zero Protocol (aka FBZERO) dissector could enter an infinite loop. This was addressed in epan/dissectors/packet-fbzero.c by correcting the implementation of offset advancement.

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 •
