A flaw was found in the python-cryptography package. This issue may allow a remote attacker to decrypt captured messages in TLS servers that use RSA key exchanges, which may lead to exposure of confidential or sensitive data. Se encontró una falla en el paquete python-cryptography. Este problema puede permitir que un atacante remoto descifre mensajes capturados en servidores TLS que utilizan intercambios de claves RSA, lo que puede provocar la exposición de datos confidenciales o sensibles. • https://access.redhat.com/security/cve/CVE-2023-50782 https://bugzilla.redhat.com/show_bug.cgi?id=2254432 • CWE-203: Observable Discrepancy CWE-208: Observable Timing Discrepancy •

An issue was discovered in Python before 3.8.18, 3.9.x before 3.9.18, 3.10.x before 3.10.13, and 3.11.x before 3.11.5. It primarily affects servers (such as HTTP servers) that use TLS client authentication. If a TLS server-side socket is created, receives data into the socket buffer, and then is closed quickly, there is a brief window where the SSLSocket instance will detect the socket as "not connected" and won't initiate a handshake, but buffered data will still be readable from the socket buffer. This data will not be authenticated if the server-side TLS peer is expecting client certificate authentication, and is indistinguishable from valid TLS stream data. Data is limited in size to the amount that will fit in the buffer. • https://lists.debian.org/debian-lts-announce/2023/09/msg00022.html https://lists.debian.org/debian-lts-announce/2023/10/msg00017.html https://mail.python.org/archives/list/security-announce%40python.org/thread/PEPLII27KYHLF4AK3ZQGKYNCRERG4YXY https://security.netapp.com/advisory/ntap-20231006-0014 https://www.python.org/dev/security https://access.redhat.com/security/cve/CVE-2023-40217 https://bugzilla.redhat.com/show_bug.cgi?id=2235789 • CWE-305: Authentication Bypass by Primary Weakness •

read_ints in plistlib.py in Python through 3.9.1 is vulnerable to a potential DoS attack via CPU and RAM exhaustion when processing malformed Apple Property List files in binary format. A vulnerability was found in the Python core plistlib library within the read_ints() function in the plistlib.py file. In malformed input, the implementation can be manipulated to create an argument for struct.unpack(). This issue can lead to excessive CPU and memory consumption, resulting in a MemError, as it constructs the 'format' argument for unpack(). This flaw allows an attacker to employ a binary plist input, potentially executing a denial of service (DoS) attack by exhausting CPU and RAM resources. • https://bugs.python.org/issue42103 https://lists.debian.org/debian-lts-announce/2023/10/msg00017.html https://security.netapp.com/advisory/ntap-20230929-0009 https://access.redhat.com/security/cve/CVE-2022-48564 https://bugzilla.redhat.com/show_bug.cgi?id=2249750 • CWE-400: Uncontrolled Resource Consumption •

A use-after-free exists in Python through 3.9 via heappushpop in heapq. A use-after-free vulnerability was found in Python via the heappushpop function in the heapq module. This flaw allows an attacker to submit a specially crafted request, causing a service disruption that leads to a denial of service attack. • https://bugs.python.org/issue39421 https://lists.debian.org/debian-lts-announce/2023/09/msg00022.html https://lists.debian.org/debian-lts-announce/2023/10/msg00017.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JZ5OOBWNYWXFTZDMCGHJVGDLDTHLWITJ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VO7Y2YZSDK3UYJD2KBGLXRTGNG6T326J https://security.netapp.com/advisory/ntap-20230929-0008 https://access.redhat.com/security/cve/CVE-2022&# • CWE-416: Use After Free •
