openssh: openssh: GSSAPI delegated credentials can be stored after a failed authentication

CVE-2026-110924 has been marked as a duplicate of CVE-2026-106553.

Rubygem-katello: katello: katello: katello docker tags repositories api cross-organization authorization bypass

A flaw was found in Katello where the Docker Tags repositories API does not properly enforce organization scoping when listing repositories for a Docker meta tag. An authenticated user with permission to view products in one organization may be able to retrieve repository metadata associated with Docker tags belonging to another organization by supplying the tag identifier. This can result in unauthorized disclosure of repository configuration information across organization boundaries.

Rubygem-katello: katello: katello: katello flatpak remote repositories api cross-organization authorization bypass

A flaw was found in Katello where the Flatpak Remote Repositories API does not properly enforce authorization when accessing a flatpak remote repository by identifier. An authenticated user with permission to view flatpak remotes in one organization may be able to access flatpak remote repository information belonging to another organization. The same unscoped lookup is used by the mirror action, which may allow creating a repository in a product the user can edit that is configured with another organization's flatpak remote URL and stored remote credentials.

Ansible: ansible-ui: ansible ui dom xss in /redirect next parameter

A DOM-based Cross-Site Scripting (XSS) vulnerability exists in the Ansible Platform UI due to unvalidated input handling within the application's redirect route. Specifically, the application extracts a target destination from the next query parameter and directly assigns it to the browser's location.href without verifying its format or scheme. The platform includes built-in URL validation functions designed to block malicious URI schemes (such as javascript: and data:) as well as off-site or protocol-relative redirects, this specific route bypasses those controls. Consequently, an attacker can craft a malicious link that, when accessed by an authenticated user, causes arbitrary JavaScript to execute within the context of the user's session.

Busybox: busybox: tls ssl_server reads one byte out of bounds when parsing truncated clienthello

BusyBox TLS get_client_hello() reads past the end of the input buffer when parsing a truncated ClientHello message.

Busybox: busybox: passwd/group parser writes heap pointers out of bounds due to stale tokenize() endpoint

BusyBox passwd/group tokenize() references a stale endpoint pointer after trimming, causing an out-of-bounds write of heap pointers.

Busybox: busybox: dpkg read_package_field() steps past nul terminator, causing out-of-bounds read on malformed .deb packages

BusyBox dpkg read_package_field() steps past a NUL terminator on malformed .deb packages, causing an out-of-bounds heap read.

Busybox: busybox: httpd misidentifies yescrypt password hashes as plaintext, inverting authentication

BusyBox httpd treats yescrypt ($y$) password hashes as plaintext during Basic Authentication, inverting the authentication check.

Busybox: busybox: httpd silently fails open when ip deny rules contain invalid cidr prefix lengths

BusyBox httpd IP deny rules with invalid CIDR prefix lengths fail open, leaving a parsed IP with a zeroed mask so the rule matches no clients.

Busybox: busybox: romfs volume id parsing performs unbounded memcpy into fixed-size label buffer, causing heap overflow

BusyBox romfs volume ID parsing uses unbounded strlen on attacker-controlled metadata, causing a heap buffer overflow when processing crafted filesystem images.

cups: cups-filters: cups-filters: lpadmin can escalate to root via privileged serial backend (cups2root)

Not a vulnerability. Creating a serial queue that overwrites cups-files.conf requires membership in SystemGroups (lpadmin), which is an opt-in cupsd admin role granted by a superuser. No privilege boundary is crossed.

Libssh: libssh: integrity downgrade via openssl aes-gcm tag verification

A flaw was found in libssh. Incorrect AES-GCM finalization checks in builds using the OpenSSL backend can effectively remove integrity protection, allowing an in-path attacker to modify plaintext on the wire without detection.

Red Hat Product Security has come to the conclusion that this CVE is false due to upstream security policy.

Libssh: libssh: use-after-free via data callbacks on closed channels

A flaw was found in libssh. If data packets are processed after a channel is closed, channel data callbacks can be invoked after the associated data has already been freed, leading to crashes or possible use-after-free conditions.

Libssh: libssh: denial of service via sftp responses with unknown request ids

A flaw was found in libssh. A malicious SFTP server can send responses for unknown request IDs that libssh clients keep queued indefinitely, causing unbounded memory growth and client-side denial of service.

Libssh: libssh: information disclosure via proxycommand %r username expansion

A flaw was found in libssh. A malicious username expanded through %r in ProxyCommand handling can inject shell metacharacters, exposing environment variables and causing unintended shell behavior.

Libssh: libssh: denial of service via unchecked proxycommand fork() failure

A flaw was found in libssh. When ProxyCommand is used, an unchecked fork() failure can be stored as process ID -1; during cleanup, signals may then be sent across the caller's accessible process tree, leading to local denial of service.

Libssh: libssh: denial of service via oversized sftp read length

A flaw was found in libssh. A remote authenticated client can issue SSH_FXP_READ requests with an arbitrarily large length, causing a libssh SFTP server to allocate excessive memory and potentially exhaust it through repeated requests.

Libssh: libssh: denial of service via zero advertised channel packet size

A flaw was found in libssh. A remote authenticated peer can advertise a zero maximum packet size in SSH_MSG_CHANNEL_OPEN, causing later channel writes to loop indefinitely and consume CPU, leading to denial of service.

NGINX ngx_http_rewrite_module vulnerability

NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_rewrite_module module. This vulnerability exists when a rewrite directive uses a regex pattern with distinct, overlapping Perl-Compatible Regular Expression (PCRE) captures (for example, ^/((.*))$) and a replacement string that references multiple such captures (for example, $1$2) in a redirect or arguments context. An unauthenticated attacker along with conditions beyond their control can exploit this vulnerability by sending crafted HTTP requests. This may cause a heap buffer overflow in the NGINX worker process leading to a restart. Additionally, attackers can execute code on systems with Address Space Layout Randomization (ASLR) disabled or when the attacker can bypass ASLR. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
