CVE Vulnerability Catalog

ImageMagick prior to versions 6.9.13-27 and 7.1.2-1 has undefined behavior (function-type-mismatch) in the splay tree cloning callback. This results in a deterministic abort under UBSan (DoS in sanitizer builds).

In the Linux kernel, a double accounting race was fixed in Btrfs when btrfs_run_delalloc_range() fails. The issue occurs when block size is smaller than page size and can lead to kernel crash.

In the Linux kernel, the Android Binder driver no longer stores a pointer to a VMA for later use outside the mmap_lock. This was unsafe because the pointer could reference freed memory.

The IsPixelMonochrome function in MagickCore/pixel-accessor.h in ImageMagick 7.0.3.0 allows remote attackers to cause a denial of service (out-of-bounds read and crash) via a crafted file. The vendor states this is a Q64 issue and Q64 is not supported.

In the Linux kernel, a vulnerability was found in the tracing mechanism where trace_event_file lacks reference counters. This can lead to use-after-free and kernel crash.

The getlong function in numutils.c in libdoc through 2017-10-23 has a heap-based buffer over-read that allows attackers to cause a denial of service (application crash) via a crafted file.

In the Linux kernel, the Bluetooth subsystem (hci_core) now disables works during hci_unregister_dev because the hci_dev is about to be freed and new submissions should not be allowed.

In the Linux kernel, in the NFS server (nfsd), a race between the laundromat thread and the free_stateid operation was fixed, which could lead to incorrect handling of expired delegations.

In the Linux kernel, an overflow in the ring-buffer's __rb_map_vma function was fixed, which occurred when calculating the number of pages (nr_pages). A check was added before the calculation to avoid the issue.

In the Linux kernel's drm/amdgpu/mes driver, a use-after-free issue exists. The fix removes the fence fallback timer to eliminate random errors.

The ReadPCXImage function in coders/pcx.c in ImageMagick 7.0.4.9 allows remote attackers to cause a denial of service (attempted large memory allocation and application crash) via a crafted file. This vulnerability exists because of an incomplete fix for CVE-2016-8862 and CVE-2016-8866.

The WritePICONImage function in coders/xpm.c in ImageMagick 7.0.6-4 allows remote attackers to cause a denial of service (memory leak) via a crafted file that is mishandled in an AcquireSemaphoreInfo call.

A flaw was found in OpenSSH where the authorized_keys "restrict" keyword is not applied to tunnel forwarding. When PermitTunnel is enabled, a key restricted with "restrict" can still open a tunnel.

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.

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.

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::Transport::Session#poll_message pushes every packet received during key exchange that is not on the "allowed during KEX" list into an unbounded @queue (Array) with no size cap. A malicious server that completes KEXINIT (putting net-ssh into pending KEX) and then floods non-allowed packets can cause unbounded memory growth.

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 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).
