Technical description

The security fix for CVE-2025-0728 in eclipse-threadx NetX Duo refactors error handling in the HTTP server PUT process to use a shared cleanup label, but this unified cleanup path unconditionally calls fx_file_close() even when the file was never successfully opened. Multiple error branches jump to the shared cleanup label before any file open operation has occurred, causing fx_file_close() to operate on an uninitialized file handle, leading to undefined behavior, double-close issues, or memory corruption.

——30Double Free and possible RCE vulnerability in Apache HTTP Server with the HTTP/2 protocol. This issue affects Apache HTTP Server: 2.4.66. Users are recommended to upgrade to version 2.4.67, which fixes the issue.2d CVE-2026-34977.5 HIG

——24Vulnerability in the OpenSSH GSSAPI delta included in various Linux distributions. This vulnerability affects the GSSAPI patches added by various Linux distributions and does not affect the OpenSSH upstream project itself. The usage of sshpkt_disconnect() on an error, which does not terminate the process, allows an attacker to send an unexpected GSSAPI message type during the GSSAPI key exchange to the server, which will call the underlying function and continue the execution of the program without setting the related connection variables. As the variables are not initialized to NULL the code later accesses those uninitialized variables, accessing random memory, which could lead to undefined behavior. The recommended workaround is to use ssh_packet_disconnect() instead, which does terminate the process. The impact of the vulnerability depends heavily on the compiler flag hardening configuration.2d CVE-2026-89259.8 CRI

——17GIMP PGM File Parsing Uninitialized Memory Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GIMP. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of PGM files. The issue results from the lack of proper initialization of memory prior to accessing it. An attacker can leverage this vulnerability to execute code in the context of the current process.
