CVE-2026-33633 Kitty has a Heap Buffer Overflow in its Graphics Protocol Handler

Kitty is a cross-platform GPU based terminal. Versions 0.46.2 and below contain a heap buffer overflow in loadimagedata that allows any process which can write to the terminal's stdin to crash kitty immediately. The vulnerability is triggered by a single APC graphics protocol command with a PNG...

CVE-2026-33633

CVE-2026-33633 affects the Kitty terminal. Versions 0.46.2 and earlier are vulnerable to a heap buffer overflow in load_image_data(), triggered by a single APC graphics protocol command with a PNG declaration (f=100) whose payload exceeds twice the initial buffer capacity. The overflow is attacke...

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...

Envoy AI Proxy - MCP Message Smuggling Vulnerability

Envoy AI Gateway was found to be affected by a protocol parser differential vulnerability due to improper implementation of the JSON-RPC 2.0 specification. Such differential causes a MCP message alteration, potentially causing a bypass of security controls in a multi-layered architecture. Accordi...

curl: libcurl: Information disclosure via incorrect Proxy-Authorization header reuse

A flaw was found in libcurl. When a user performs a transfer over an HTTP proxy using Digest authentication and then reuses the same handle for a second transfer with a different proxy host, libcurl incorrectly sends the Proxy-Authorization header intended for the first proxy to the second proxy...

corosync: Corosync: Denial of Service and information disclosure via crafted UDP packet

A flaw was found in Corosync. A remote unauthenticated attacker can exploit a wrong return value vulnerability in the Corosync membership commit token sanity check by sending a specially crafted User Datagram Protocol UDP packet. This can lead to an out-of-bounds read, causing a denial of service...

OpenSSH: OpenSSH: Privilege escalation via scp legacy protocol when not preserving file mode

A flaw was found in OpenSSH. When the scp command is used by a root user to download a file with the legacy protocol option -O and without preserving original file permissions -p, the downloaded file can be installed with elevated privileges setuid or setgid. This unexpected behavior could allow ...

freerdp: FreeRDP: Arbitrary code execution via heap buffer overflow in GDI surface pipeline

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol RDP. A malicious RDP server can exploit a heap buffer overflow vulnerability by sending a specially crafted graphics command to a FreeRDP client. This allows the server to write data outside of its intended memory...

freerdp: FreeRDP: Arbitrary code execution via crafted Remote Desktop Protocol (RDP) server messages

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol RDP. The gdisurfacebits function, which processes SURFACEBITSCOMMAND messages, does not properly validate image dimensions bmp.width and bmp.height provided by a malicious RDP server. This can lead to a heap buffer...

freerdp: FreeRDP: Arbitrary code execution via heap out-of-bounds write in RLE planar decode path

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol RDP. A malicious RDP server can exploit a heap out-of-bounds write vulnerability in the planardecompressplanerle function. This vulnerability allows the server to write past the end of a temporary buffer, potentiall...

gstreamer-plugins-good: GStreamer: Remote Code Execution via Out-Of-Bounds Write in rtpqdm2depay

A flaw was found in GStreamer. This out-of-bounds write vulnerability exists within the rtpqdm2depay element, specifically during the processing of X-QDM Real-time Transport Protocol RTP payload elements. A remote attacker can exploit this by providing malformed user-supplied data to the packetid...

gstreamer-plugins-good: GStreamer: Remote Code Execution via Heap-based Buffer Overflow in rtpqdm2depay

A flaw was found in GStreamer. This heap-based buffer overflow vulnerability in the rtpqdm2depay component allows a remote attacker to execute arbitrary code.
