python: ftplib should not use the host from the PASV response

A flaw was found in Python, specifically in the FTP File Transfer Protocol client library in PASV passive mode. The issue is how the FTP client trusts the host from the PASV response by default. This flaw allows an attacker to set up a malicious FTP server that can trick FTP clients into connecti...

GHSA-MPG6-RGP4-35RR Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') in pyftpdlib

Race condition in the FTPHandler class in ftpserver.py in pyftpdlib before 0.5.1 allows remote attackers to cause a denial of service daemon outage by establishing and then immediately closing a TCP connection, leading to the accept function having an unexpected return value of None, a different...

PT-2022-2695

Name of the Vulnerable Software and Affected Versions libcurl affected versions not specified Description The issue is related to how libcurl handles previously used connections in a connection pool for subsequent transfers. When a TLS or SSH-related option is changed, it should prohibit the reus...

Insecure IPv6 Connection

curl has insecure IPv6 connection. The vulnerability exists due to an errors in the logic where the config matching function did not take the IPv6 address zone id into account allowing the system to use the wrong connection when one transfer uses a zone id, and when subsequent transfer uses anoth...

Internet Bug Bounty: OAUTH2 bearer not-checked for connection re-use

libcurl might reuse OAUTH2-authenticated connections without properly making sure that the connection was authenticated with the same credentials as set for this transfer. This affects SASL-enabled protcols: SMTPS, IMAPS, POP3S and LDAPS openldap only. libcurl maintains a pool of connections afte...

Cisco Firepower Threat Defense Software Denial of Service Vulnerability

A vulnerability in the connection handling function in Cisco Firepower Threat Defense FTD Software could allow an unauthenticated, remote attacker to cause a denial of service DoS condition on an affected device. This vulnerability is due to improper traffic handling when platform limits are...

Bad local IPv6 connection reuse

libcurl keeps previously used connections in a connection pool for subsequent transfers to reuse, if one of them matches the setup. Due to errors in the logic, the config matching function did not take the IPv6 address zone id into account which could lead to libcurl reusing the wrong connection...

Internet Bug Bounty: CVE-2022-27775: Bad local IPv6 connection reuse

Summary: curl/libcurl doesn't consider IPv6 address zone index when doing connection reuse. if connection exists to specific IPv6 address and other conditions for connection reuse are fulfilled it will be reused for connections regardless of the zone index. Steps To Reproduce: 1. Set up a fake...
