curl: curl: Security bypass due to global TLS option changes in multi-threaded LDAPS transfers

A flaw was found in curl. When performing multi-threaded LDAPS Lightweight Directory Access Protocol Secure transfers, changes to Transport Layer Security TLS options in one thread could inadvertently apply globally, affecting other concurrent transfers. This could lead to unintended security...

curl: curl: Authentication bypass due to incorrect connection reuse with Negotiate authentication

A flaw was found in curl. When an application uses libcurl to make multiple Negotiate-authenticated HTTP or HTTPS requests to the same server with different credentials, libcurl may incorrectly reuse an existing connection. This logical error can cause a subsequent request to be sent using the...

Moderate: Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update

An update for Red Hat Hardened Images RPMs is now available. This update includes the following RPMs: curl: curl-8.22.0-1.1.hum1 aarch64, s390x, x8664 libcurl-8.22.0-1.1.hum1 aarch64, s390x, x8664 libcurl-devel-8.22.0-1.1.hum1 aarch64, s390x, x8664 libcurl-minimal-8.22.0-1.1.hum1 aarch64, s390x,...

curl: curl: Information disclosure via OAuth2 bearer token leakage during HTTP(S) redirect

A flaw was found in curl. When an OAuth2 bearer token is used for an HTTPS transfer that redirects to a second URL, curl could unintentionally leak the token. This occurs if the second hostname has entries in the .netrc file, allowing the bearer token intended for the first host to be sent to the...

curl: curl: Unauthorized access due to improper HTTP proxy connection reuse

A flaw was found in curl. This vulnerability allows curl to wrongly reuse an existing HTTP proxy connection when performing a CONNECT request to a server, even if the new request uses different authentication credentials for the HTTP proxy. This improper connection reuse could lead to an attacker...

K000163564: Curl vulnerabilities CVE-2025-13034 and CVE-2025-10966

Security Advisory Description CVE-2025-13034 When using CURLOPTPINNEDPUBLICKEY option with libcurl or --pinnedpubkey with the curl tool, curl should check the public key of the server certificate to verify the peer. This check was skipped in a certain condition that would then make curl allow the...

The Ocaml Curl Library Ocurl is an interface library for the programming language Ocaml to the networking library libcurl...

Astra Linux – Vulnerability in curl

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 ‘issuercert’ into account, and it compared the involved paths case insensitively, which could...

Astra Linux – Vulnerability in curl

There is a path traversal vulnerability in the 8.0.0 SFTP implementation of curl. This vulnerability causes the tilde character to be incorrectly replaced when used as a prefix in the first path element. Additionally, the tilde is intended to be used as the first element to indicate a path relati...

Astra Linux – Vulnerability in curl

There is a vulnerability in input validation in curl 8.0. During communication using the TELNET protocol, this may allow an attacker to send maliciously crafted user names and “telnet options” during server negotiation. The lack of proper input scrubbing allows an attacker to send content or...

Astra Linux – Vulnerability in curl

When an OAuth2 bearer token is used for an HTTPS transfer, and that transfer performs a cross-protocol redirect to a second URL that uses an IMAP, LDAP, POP3, or SMTP scheme, curl may incorrectly pass the bearer token to the new target host...

Astra Linux – Vulnerability in curl

A poorly protected credentials vulnerability exists in curl 4.9, and versions including curl 7.82.0 are also affected. This vulnerability could allow attackers to extract credentials when using HTTPS redirections with authentication. As a result, credentials may be leaked to other services that...

Astra Linux – Vulnerability in curl

When the curl command is used to retrieve content using the Metalink feature, and a user name and password are used to download the Metalink XML file, those same credentials are then passed to each server from which the curl command will attempt to download or retrieve the content. This often...

Astra Linux – Vulnerability in curl

There is a vulnerability in curl version 7.87.0 where it is possible to exploit the memory reclamation mechanism. In this vulnerability, curl can be instructed to tunnel virtually all protocols it supports through an HTTP proxy. HTTP proxies can and often do deny such tunnel operations. When curl...

Astra Linux – Vulnerability in curl

There is an information disclosure vulnerability in curl v8.1.0 when performing HTTPS transfers. libcurl may incorrectly use the read callback CURLOPTREADFUNCTION to request data to be sent, even when the CURLOPTPOSTFIELDS option is set. This occurs if the same handle was previously used to issue...

Astra Linux – Vulnerability in curl

When asked to use a .netrc file for credentials and to follow HTTP redirects, curl could leak the password used for the first host to the followed-to host under certain circumstances. This flaw only manifests itself if the netrc file has an entry that matches the redirect target hostname, but the...

Astra Linux – Vulnerability in curl

When curl is used to retrieve and parse cookies from an HTTPS server, it accepts cookies using control codes that, when sent back to an HTTP server later, may cause the server to return 400 responses. This effectively allows a “sister site” to deny service to all other sibling sites...

MAL-2026-17611 Malicious code in tron-rb (RubyGems)
