CVE-2026-54876

Issue summary: A malicious TLS server can cause a memory leak in a TLS client that has enabled OCSP response checking by sending an OCSP response that contains no single response entries. Impact summary: An attacker can leak an attacker-tunable amount of memory per TLS handshake in a victim clien...

Amazon Linux 2023 : gstreamer1-plugin-openh264, gstreamer1-plugins-bad-free, gstreamer1-plugins-bad-free-devel (ALAS2023-2026-1994)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1994 advisory. A flaw was found in GStreamer's gst-plugins-bad package. When processing a specially crafted H.264 video file containing malformed MVC or SVC extension slice NAL units, a 1-byte heap...

Amazon Linux 2 : gstreamer1-plugins-bad-free, --advisory ALAS2-2026-3833 (ALAS-2026-3833)

The version of gstreamer1-plugins-bad-free installed on the remote host is prior to 1.18.4-5. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2026-3833 advisory. A flaw was found in GStreamer's gst-plugins-bad package. When processing a specially crafted H.264...

Important: runfinch-finch

Issue Overview: On Unix systems, opening a file in an os.Root improperly follows symlinks to locations outside of the Root when the final path component of the a path is a symbolic link and the path ends in /. For example, 'root.Open"symlink/"' will open "symlink" even when "symlink" is a symboli...

CVE-2026-48113

Chisel is a TCP/UDP tunnel, transported over HTTP and secured via SSH. In versions prior to 1.11.5, authenticated clients can bypass --authfile ACL restrictions and tunnel traffic to arbitrary destinations reachable from the server. The ACL is enforced only during the initial handshake against...

CVE-2026-48113

The CVE-2026-48113 entry concerns Chisel, a TCP/UDP tunnel over SSH, where ACL restrictions provided by --authfile are bypassed on post-handshake SSH channels. Authenticated clients can open channels to arbitrary host:port destinations reachable from the server because ACL checks are performed on...

CVE-2026-48113 Chisel: ACL Bypass via Post-Handshake SSH Channel ExtraData Injection

Chisel is a TCP/UDP tunnel, transported over HTTP and secured via SSH. In versions prior to 1.11.5, authenticated clients can bypass --authfile ACL restrictions and tunnel traffic to arbitrary destinations reachable from the server. The ACL is enforced only during the initial handshake against...

netty-handler: Netty: Denial of Service due to eager buffer allocation in TLS handshake

A flaw was found in Netty, a network application framework. A remote attacker can exploit this vulnerability by sending a crafted TLS Transport Layer Security ClientHello message. This can lead to an eager allocation of a large memory buffer, causing a Denial of Service DoS due to excessive memor...
