K000163073: curl vulnerability CVE-2026-8925

Security Advisory Description The curl logic that works with SASL authentication could end up cleaning up the GSASL context twice without clearing the pointer in between, making it free the same pointer twice. CVE-2026-8925 Impact There is no impact; F5 products are not affected by this...

EulerOS Virtualization 2.13.0 : curl (EulerOS-SA-2026-3209)

According to the versions of the curl packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities : libcurl might in some circumstances reuse the wrong connection when asked to do an authenticated HTTPS request after a...

Astra Linux – Vulnerability in curl

curl 7.84.0 supports “chained” HTTP compression algorithms, which means that a server response can be compressed multiple times, possibly using different algorithms. The number of allowable “links” in this “decompression chain” is unlimited, allowing a malicious server to insert virtually an...

Astra Linux – Vulnerability in curl

A authentication bypass vulnerability exists in libcurl version 8.0.0, particularly in the connection reuse feature. This vulnerability allows for the reuse of previously established connections with incorrect user permissions, due to a failure to check for changes in the CURLOPTGSSAPIDELEGATION...

Astra Linux – Vulnerability in curl

When curl version 7.20.0 or later connects to an IMAP or POP3 server to retrieve data using STARTTLS to upgrade to TLS security, the server can send multiple responses at once, which are cached by curl. In this case, curl upgrades to TLS, but it does not discard the cached responses. Instead, it...

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 Firefox, Thunderbird

Insufficient escaping in the “Copy as cURL” feature could potentially be used to trick a user into executing unexpected code. This vulnerability was fixed in Firefox 141, Firefox ESR 128.13, Firefox ESR 140.1, Thunderbird 141, Thunderbird 128.13, and Thunderbird 140.1...

Astra Linux – Vulnerability in curl

Curl versions 7.21.0 through 7.73.0 are vulnerable to uncontrolled recursion due to a stack overflow issue in FTP wildcard match parsing...

Astra Linux – Vulnerability in curl

A vulnerability related to insufficiently protected credentials, addressed in curl 7.83.0, may cause authentication or cookie header data to be leaked during HTTP redirections to the same host, but using a different port number...

Astra Linux – Vulnerability in curl

Curl versions 7.20.0 through 7.70.0 are vulnerable to improper restrictions on the names of files and other resources, which can lead to overwriting of local files when the -J flag is used...

Astra Linux – Vulnerability in curl

This flaw allows an attacker to insert cookies into a running program using libcurl, provided that certain conditions are met. Libcurl performs transfers. In its API, an application creates “easy handles”—individual handles used for single transfers. Libcurl provides a function called...

Astra Linux – Vulnerability in curl

There is a vulnerability in the handling of certificate validation in curl v8.1.0, particularly in how wildcard patterns are matched when listed as “Subject Alternative Name” in TLS server certificates. Curls can be modified to use its own name matching function for TLS, rather than the one...

Astra Linux – Vulnerability in curl

Successfully using libcurl to perform a transfer over a specific HTTP proxy proxyA with Digest authentication. Then, changing the proxy host to another one proxyB for a second transfer, while reusing the same handle, causes libcurl to incorrectly pass the Proxy-Authorization: header field meant f...

Astra Linux – Vulnerability in curl

This flaw allows a malicious HTTP server to set “super cookies” using curl, which are then transmitted back to multiple origins beyond what is allowed or possible. This enables a site to set cookies that are then sent to different and unrelated sites and domains. The attack exploits a flaw in...

Astra Linux – Vulnerability in curl

In versions 7.7 through 7.76.1 of curl, there is an information disclosure issue when the -t command-line option, referred to as CURLOPTTELNETOPTIONS in libcurl, is used to send variable=content pairs to TELNET servers. This issue arises due to a flaw in the option parser for sending NEWENV...

Astra Linux – Vulnerability in curl

libcurl accidentally skips the certificate verification for QUIC connections when connecting to a host specified as an IP address in the URL. As a result, it does not detect impostor attacks or man-in-the-middle attacks...

Astra Linux – Vulnerability in curl

When curl 7.84.0 performs FTP transfers secured by krb5, it incorrectly handles message verification failures. This flaw allows a Man-In-The-Middle attack to go unnoticed, and even enables the attacker to inject data into the client’s system...

Astra Linux – Vulnerability in curl

A malicious server can use the FTP PASV response to trick curl 7.73.0 and earlier into connecting back to a given IP address and port. In this way, the malicious server can potentially enable curl to extract information about services that would otherwise be private and undisclosed. This could...

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 redirection to a second URL, curl may leak that token to the second hostname under certain circumstances. If the hostname to which the first request is redirected to contains information in the used .netrc fil...
