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...
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: failed external mount helper still runs privileged X-mount post-hooks
When an external mount. helper runs but exits with a nonzero status, libmount still treats the helper invocation as successful and runs privileged post-mount hooks. A local unprivileged user with an /etc/fstab entry that uses the user option together with X-mount.idmap or X-mount.owner/group/mode...
util-linux: util-linux: X-mount.subdir detached-tree resolution can escape via intermediate symlinks
The X-mount.subdir option uses a detached-tree fast path on Linux 6.15 and later and passes the configured subdirectory to opentree with ATSYMLINKNOFOLLOW. That flag does not stop intermediate symlink traversal or keep resolution inside the newly mounted filesystem. A local unprivileged user with...

net/url: Incorrect parsing of IPv6 host literals in net/url
The Go standard library function net/url.Parse insufficiently validated the host/authority component and accepted some invalid URLs by effectively treating garbage before an IP-literal as ignorable. The function should have rejected this as invalid...
net/mail: golang: net/mail: Denial of Service via pathological email address parsing
A flaw was found in the net/mail package within the Go standard library. A remote attacker could provide specially crafted, pathological email addresses. When these malformed email addresses are parsed by the consumePhrase function, it can lead to excessive resource consumption due to quadratic...
curl: libcurl: Information disclosure via incorrect connection reuse with Negotiate authentication
A flaw was found in libcurl. This vulnerability allows an attacker to reuse an HTTP connection set up for a given hostname using Negotiate authentication. When an initial request is made with empty credentials, a subsequent user's request can be sent over a previously authenticated connection...
curl: curl: Information disclosure due to secure cookie attribute bypass
A flaw was found in curl. When a Set-Cookie: header uses a tab character instead of a space before the Secure attribute, curl incorrectly stores the cookie without the Secure flag.
