netrc and default credential leak

Last updated 10 July 2026

Accounts. The issue was addressed with improved checks.

A vulnerability found in curl. This security flaw happens when curl is used to retrieve and parse cookies from an HTTP(S) server, where it accepts cookies using control codes (byte values below 32), and also when cookies that contain such control codes are later sent back to an HTTP(S) server, possibly causing the server to return a 400 response. This issue effectively allows a "sister site" to deny service to siblings and cause a denial of service attack.

A flaw was found in Eclipse Jetty. When parsing the authority segment of an HTTP scheme URI, the Jetty HttpURI class improperly detects an invalid input as a hostname. This issue can lead to failures in a Proxy scenario.

Eclipse Jetty is vulnerable to a denial of service, caused by an error related to some of the production servers spiking with CPU use. A remote attacker could exploit this vulnerability to consume CPU that remains high even without any traffic.

SELinux Project SELinux is vulnerable to a denial of service, caused by a use-after-free in cilresetclasspermission . By sending a specially-crafted request, a local attacker could exploit this vulnerability to cause a denial of service condition.

A malicious server can use the PASV response to trick curl into connecting back to a given IP address and port, and this way potentially make curl extract information about services that are otherwise private and not disclosed, for example doing port scanning and service banner extractions. If curl operates on a URL provided by a user (which by all means is an unwise setup), a user can exploit that and pass in a URL to a malicious FTP server instance without needing any server breach to perform the attack.

Two memory leak flaws were found in the Linux kernel's mwifiexpcieinitevtring() function. A local attacker, able to reload the kernel module or hotplug Marvell WiFi hardware using this driver, can cause a denial of service (memory consumption) by triggering mwifiexmappcimemory() failures.
