emacs: GNU Emacs: Heap over-read leading to information disclosure via crafted image

A flaw was found in GNU Emacs. An integer overflow in the PBM/PPM/PGM image loader allows a remote attacker to leak heap memory contents. By supplying a specially crafted image with large dimensions and an elevated maximum color index, the image loader's internal calculations can wrap to a negati...

qt5-qtsvg: qt6-qtsvg: qt: Denial of Service via deeply nested SVG elements

A flaw was found in the Qt SVG module. A remote attacker could trigger this issue by providing a specially crafted SVG Scalable Vector Graphics file containing deeply nested elements. When parsed, this leads to uncontrolled recursion and stack exhaustion, resulting in an application crash and a...

curl: libcurl: Authentication bypass due to incorrect HTTP Negotiate connection reuse

A flaw was found in libcurl. An application using libcurl that performs an authenticated HTTPS request after a Negotiate-authenticated one to the same host may incorrectly reuse the previous connection. This authentication bypass vulnerability allows the second request to be sent over a connectio...

curl: curl: Proxy credential disclosure via redirects to unauthenticated proxies

A flaw was found in curl. When curl is configured to use distinct proxies for different URL schemes, a redirect from a URL using an authenticated proxy to one using an unauthenticated proxy can inadvertently expose the initial proxy's credentials. This improper credential management CWE-522 may...

openssh: OpenSSH sshd: Security bypass due to incorrect handling of forwarding and tunneling options

A flaw was found in sshd, the OpenSSH server daemon. When DisableForwarding=yes is configured to prevent network traffic forwarding, it incorrectly fails to take precedence over PermitTunnel=yes. This allows a remote attacker to bypass intended security restrictions and establish a tunnel,...

openssh: Double free in Red Hat Enterprise Linux versions of OpenSSH DH-GEX client path during FIPS known-group validation leads to client-side denial of service

A flaw was found in OpenSSH. A malicious SSH server can exploit a double free vulnerability in the Diffie-Hellman Group Exchange DH-GEX client path. This occurs during FIPS Federal Information Processing Standards mode known-group validation when the client processes attacker-controlled DH-GEX...

openssh: Local MITM of X11 forwarding via abstract UNIX socket pre-binding in Red Hat Enterprise Linux OpenSSH client versions

A flaw was found in OpenSSH. A local unprivileged attacker on a Linux client host can hijack client-side X11 forwarding connections. This is possible by pre-binding the preferred abstract X socket name when X11 forwarding is enabled and a local UNIX-domain X socket is used. A successful attack ca...

openssh: OpenSSH: `scp` file misplacement vulnerability during remote copy

A flaw was found in OpenSSH, a widely used tool for secure remote access. When a user attempts to copy files between two different remote systems using the scp command, the file might be incorrectly placed in a directory above the intended destination. This unintended file placement could lead to...

openssh: OpenSSH: sftp client allows attacker to control downloaded file location

A flaw was found in OpenSSH. The sftp client, when used to download files from a malicious server with the 'sftp server:/path .' command, does not properly restrict where those files are saved. This allows an attacker to control the download location, potentially overwriting existing files or...

CVE-2026-108981

ngxcachepurge before 3.0.4 can allow file deletion via a symlink attack in certain situations where nginx and a served application e.g., WordPress run under the same user account. The attacker must be able to create a symlink inside the cache path. Version 3.0.4 fixes this for the case of a symli...

emacs: emacs: Command injection via crafted filenames in TRAMP

A flaw was found in Emacs TRAMP. A local attacker could exploit this vulnerability by processing maliciously crafted filenames. This occurs because TRAMP concatenates login arguments without proper sanitization, which are then passed to a local shell. Successful exploitation could lead to arbitra...

flatpak: Flatpak: Arbitrary code execution via missing symlink protection

A flaw was found in Flatpak. A malicious sandboxed application can exploit missing symlink protection during the creation and bind-mounting of app data directories. By manipulating attacker-controlled path components, a malicious symlink can redirect these directories to arbitrary locations on th...

flatpak: flatpak: Buffer overflow in OCI delta stream path names on 32-bit systems

The OCI delta stream parser read sizes as guint64 but passed them to GLib I/O and allocation functions expecting gsize 32 bits on 32-bit systems, causing undersized allocations while subsequent operations use the original 64-bit size, leading to heap buffer overflows. An attacker controlling an O...

flatpak: flatpak: Arbitrary write access as root via extra-data extraction

A malicious or compromised Flatpak repository can write attacker-controlled content to arbitrary locations on the host filesystem via extractextradata. On system installs, the write happens as root. Two issues combine: files/extra is resolved via path operations that follow symlinks, and blob nam...

ansible-collection-ansible-posix: ansible.posix authorized_key: local privilege escalation via symlink-following chown

A local privilege escalation vulnerability was found in the ansible.posix authorizedkey module. The module's keyfile function uses os.chown instead of os.lchown and opens files without ONOFOLLOW when managing SSH authorized keys. An unprivileged local user can pre-stage symbolic links in their...

CVE-2026-108985

ZDR decoding in libnfs through 6.0.2 before 7613236 has an out-of-bounds write related to lib/libnfs-zdr.c with libnfszdrbytes, libnfszdrstring, and libnfszdrarray. The caller-supplied maxsize value is not honored...

CVE-2026-108981

ngxcachepurge before 3.0.4 can allow file deletion via a symlink attack in certain situations where nginx and a served application e.g., WordPress run under the same user account. The attacker must be able to create a symlink inside the cache path. Version 3.0.4 fixes this for the case of a symli...

flatpak-builder: Host code execution via `git am` hook execution in patch source extraction (`use-git-am`)

A flaw was found in flatpak-builder where Git hooks are not disabled when applying patch sources with use-git-am: true. An attacker who can provide a malicious source containing a Git post-applypatch hook can cause the hook to execute on the host during the build process, resulting in arbitrary...

flatpak-builder: Host code execution via `git am` hook execution in patch source extraction (`use-git-am`)

A flaw was found in flatpak-builder where Git hooks are not disabled when applying patch sources with use-git-am: true. An attacker who can provide a malicious source containing a Git post-applypatch hook can cause the hook to execute on the host during the build process, resulting in arbitrary...

firefox: thunderbird: Sandbox escape in the Remote Settings Client component

A flaw was found in Firefox and Thunderbird. The Mozilla Foundation's Security Advisory describes the following issue: Sandbox escape in the Remote Settings Client component...
