Internet Bug Bounty: CVE-2023-27535: FTP too eager connection reuse

A vulnerability was found in libcurl versions 7.13.0 to 7.88.1 that allowed the reuse of previously created FTP connections even when one or more options had been changed, leading to the second transfer being done with wrong credentials. This was due to several FTP settings being left out from th...

UBUNTU-CVE-2023-27536

An authentication bypass vulnerability exists libcurl 8.0.0 in the connection reuse feature which can reuse previously established connections with incorrect user permissions due to a failure to check for changes in the CURLOPTGSSAPIDELEGATION option. This vulnerability affects...

CVE-2023-27535

An authentication bypass vulnerability exists in libcurl 8.0.0 in the FTP connection reuse feature that can result in wrong credentials being used during subsequent transfers. Previously created connections are kept in a connection pool for reuse if they match the current setup. However, certain...

UBUNTU-CVE-2023-27538

An authentication bypass vulnerability exists in libcurl prior to v8.0.0 where it reuses a previously established SSH connection despite the fact that an SSH option was modified, which should have prevented reuse. libcurl maintains a pool of previously used connections to reuse them for subsequen...

curl -- multiple vulnerabilities

Harry Sintonen reports: CVE-2023-27533 curl supports communicating using the TELNET protocol and as a part of this it offers users to pass on user name and "telnet options" for the server negotiation. Due to lack of proper input scrubbing and without it being the documented functionality, curl...

Slackware Linux 14.0 / 14.1 / 14.2 / 15.0 / current curl Multiple Vulnerabilities (SSA:2023-079-01)

The version of curl installed on the remote host is prior to 8.0.1. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2023-079-01 advisory. - A vulnerability in input validation exists in curl 8.0 during communication using the TELNET protocol may allow an attacker t...

golang: net/http: excessive memory growth in a Go server accepting HTTP/2 requests

A flaw was found in the net/http library of the golang package. This flaw allows an attacker to cause excessive memory growth in a Go server accepting HTTP/2 requests. HTTP/2 server connections contain a cache of HTTP header keys sent by the client. While the total number of entries in this cache...

The vulnerability of the implementation of the Upper Level Protocol (ULP) in the Linux operating system allows a hacker to enhance their privileges, execute arbitrary code, or cause a service failure.

The vulnerability in the implementation of the Upper Level Protocol ULP in the Linux kernel’s inetconnectionsock.c file is related to improper handling of sockets that are in the LISTEN state in certain protocols. This leads to the reallocation of previously freed memory. Exploiting this...
