util-linux: TOCTOU in the mount program when setting up loop devices
A flaw was found in util-linux. When an /etc/fstab entry is configured with the user,loop options, the mount program checks the file path with user permissions but later opens it with root privileges. This creates a brief Time-of-Check-Time-of-Use TOCTOU window where an attacker can substitute th...
util-linux: util-linux: nsenter --join-cgroup leaks root cgroup migration authority
The nsenter --join-cgroup option opens the target cgroup.procs file as root and leaves that file descriptor open across later namespace and credential changes and across execve. Because the kernel checks later cgroup migrations using the credentials from the original open, a program run in an...
util-linux: util-linux: heap use-after-free in libblkid nested partition probing
A flaw was found in the libblkid library of util-linux. During nested partition probing, the BSD, Minix, Solaris x86, and UnixWare partition probers cache a raw pointer to a parent partition entry in a dynamically allocated array. When subsequent partition additions cause the array to be...
util-linux: util-linux: TOCTOU in the mount program when applying post-mount ownership/mode changes
A flaw was found in util-linux. When an /etc/fstab entry uses the user option together with X-mount.owner, X-mount.group, or X-mount.mode, mount8 changes ownership or permissions on the mount target after mounting without re-verifying the path. A local unprivileged user can exploit this...

curl: curl: Cookie injection via malicious HTTP server using super cookies
A flaw was found in curl's cookie parsing logic. A malicious HTTP server can exploit this by setting 'super cookies' that bypass the Public Suffix List check. This allows an attacker-controlled origin to inject cookies that curl then transmits to unrelated third-party domains, leading to...
curl: curl: Information disclosure via incorrect Digest authentication header reuse
A flaw was found in curl. When libcurl performs a transfer to an HTTP origin using Digest authentication and then reuses the same connection handle for a subsequent transfer to a different origin, it may incorrectly send the authentication header intended for the first origin to the second. This...

util-linux: TOCTOU in the mount program via ancestor directory swap on target path
When an /etc/fstab entry is configured with the user or users option, mount8 validates the target path before performing the mount syscall, creating a Time-of-Check-Time-of-Use TOCTOU window. A local unprivileged user with write access to an ancestor directory of the mount target can swap that...
util-linux: util-linux: SUID mount(8) allows nosuid/noexec bypass via LIBMOUNT_FORCE_MOUNT2
A flaw was found in util-linux. The mount8 SUID binary does not sanitize the LIBMOUNTFORCEMOUNT2 environment variable before use. A local unprivileged user can set this variable to force mount8 to use the legacy two-step mount2 code path, which applies security restrictions such as nosuid and...
util-linux: util-linux: restricted bind mounts do not pin the source, allowing X-mount.owner/group/mode redirection
A flaw was found in util-linux. Restricted bind mounts take the source path from fstab but do not pin that source before the privileged mount. A local unprivileged user who can replace the authorized source or a writable ancestor can redirect SUID mount8 to bind another host directory. If the fst...
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...
curl: curl: Insecure connection establishment due to TLS configuration mismatch
A flaw was found in curl. When a new data transfer attempts to upgrade its connection using STARTTLS, it may incorrectly reuse an existing live connection. This reuse can occur even if the Transport Layer Security TLS configuration of the new transfer does not match the existing connection,...
curl: libcurl: Unauthorized connection reuse due to a logical error
A flaw was found in libcurl. A logical error in the connection pooling mechanism may cause libcurl to reuse an authenticated connection for an unintended service. This could allow an application to wrongfully reuse an existing connection to the same server that was authenticated for a different...
curl: Information disclosure due to uncleared proxy authentication state
A flaw was found in libcurl. When reusing a libcurl handle for sequential transfers with environment-variable proxy configuration, the library does not properly clear the proxy authentication state. This oversight can lead to the unintended disclosure of Proxy-Authorization headers to an incorrec...
curl: curl: Man-in-the-middle attack via SSH host key bypass
A flaw was found in curl. When a libcurl-based application uses SCP:// or SFTP:// for transfers and employs the CURLOPTSSHKEYFUNCTION callback, it may silently accept an untrusted server. This occurs if the server's host key type differs from the one stored in the knownhosts file. The callback...
