CVE Vulnerability Catalog

Repeated use of the Unpacker after an error occurs may cause the process to crash with a SEGV. If the Unpacker is used repeatedly to unpack untrusted input from external sources, it may be vulnerable to a DoS attack.

The golang.org/x/crypto/openpgp package is unsafe by design, has numerous known security issues, is not maintained, and should not be used. It is recommended to use the maintained package github.com/ProtonMail/go-crypto/openpgp instead.

A segmentation fault was discovered in the libde265 library (commit d9fea9d) in the decoder_context::compute_framedrop_table() function. This vulnerability may cause crashes in applications using this library.

In GraphQL-Ruby before version 2.6.6, when using Execution::Next, authorization failures did not properly halt execution for fields using GraphQL::Schema::Resolver and its subclasses (including Mutation, RelayClassicMutation, and Subscription).

Security advisory GHSA-2hw4-c9m4-f2fj concerns the knative/pkg component. Verification on 2026-05-19 confirmed end-to-end amplification of 4.5×, worse than the advisory's conservative 2× claim. A Go proof of concept (cmd/poc-c2/main.go) was built.

Net::SSH::Transport::ServerVersion#read! appends each received byte to @version until a newline, then copies to @header, with no maximum line length or total byte cap enforced. A malicious server sending a long identification line without LF causes unbounded memory growth.

When a crafted ed25519 private key containing an insane number of rounds is loaded, net-ssh enters an infinite CPU-time consuming loop for a very long time trying to load the key. The fact that the key is not a real SSH key does not matter in this regard.

A TSIG packet with name compression can crash DNS. Incorrect size calculations when a TSIG record contains compressed names lead to a large out-of-bounds write, causing a server crash.

A low-privilege authenticated Samba AD user can modify internal LDB special DNs via LDAP access, enabling a domain takeover.

Nodemailer's SMTP client response parser reassembles multiline server replies by appending each continuation line onto a single response-queue entry and re-testing whether it is still a partial reply on every line. The partial-response test performs string operations per line, which can lead to inefficient processing.

In net-ssh, `Service::Forward#initialize` registers server-initiated auth-agent channel handlers unconditionally, so ordinary port forwarding exposes the local SSH agent.

net-ssh's host-certificate verifier (`Net::SSH::HostKeyEntries::CertAuthority#matches_key?`) checks exactly two things when a server presents an OpenSSH certificate (`*[email protected]`) under a `@cert-authority` trusted-CA entry: (1) the cert is self-consistently signed (signature_valid).

Nodemailer's address parser has three published, patched fixes for RFC 5322 comment handling inside an addr-spec. The description covers earlier issues with glued domain atoms and quoted local parts, plus related ReDoS fixes.

Nodemailer's SMTP client applies four regular expressions to a peer's EHLO response to detect supported SASL mechanisms. Each pattern uses overlapping whitespace-matching sub-patterns, producing quadratic (O(n^2)) backtracking on long mechanism names.

net-ssh's transport packet reader trusts the 4-byte wire packet length without capping it against RFC 4253 §6.1 (35000 bytes). Pre-KEX (plaintext), a malicious server can declare an arbitrarily large packet length and stream data, causing unbounded client memory growth before authentication.

A vulnerability in the virtio-gpu module of the Linux kernel involves an incorrect overflow check when allocating 2D images. This flaw can lead to a buffer overflow, potentially enabling privilege escalation or system crash.

An issue was discovered in py-lmdb 0.97 where mdb_node_del does not validate a memmove in the case of an unexpected node->mn_hi, leading to an invalid write operation. This occurs when accessing a data.mdb file supplied by an attacker.

A vulnerability in the XML::Parser library for Perl (up to version 2.45) causes a heap buffer overflow, leading to double free or corruption and crashes. The issue occurs in the parse_stream() function in Expat.xs when the :utf8 PerlIO layer is used, because Perl returns decoded characters while SvPV() expects raw bytes.
