CVE Vulnerability Catalog

The openTempFile function in Xpdf and Poppler 0.24.3 and earlier creates temporary files with predictable names when running on non-Unix systems. A local user can exploit a symlink attack to overwrite arbitrary files.

libraw 20.0 has a null pointer dereference vulnerability in parse_tiff_ifd in src/metadata/tiff.cpp, which may result in context-dependent arbitrary code execution. The vulnerability occurs only if the software is compiled in a certain way.

In Xpdf prior to 4.04, the DCT (JPEG) decoder incorrectly allowed the 'interleaved' flag to be changed after the first scan of the image, leading to an unknown integer-related vulnerability in Stream.cc. The flaw may be triggered when processing crafted PDF files.

Poppler 0.54.0 (as used in Evince and other products) has a NULL pointer dereference in JPXStream::readUByte in JPXStream.cc. Parsing an invalid PDF file causes a crash (segmentation fault).

Multiple unspecified vulnerabilities in GraphicsMagick before 1.2.4 allow remote attackers to cause a denial of service (crash, infinite loop, or memory consumption) via unspecified vectors in the AVI, AVS, DCM, EPT, FITS, MTV, PALM, RLA, and TGA decoders.

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).

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.

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.

Shell command injection is possible in Net::SSH::Proxy::Command and Net::SSH::Proxy::Jump. When an application configures a proxy and passes attacker-influenced host, port, or remote_user values to Net::SSH.start (or a jump string to Proxy::Jump.new), shell metacharacters in those values may be interpreted.

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 OpenPixelCache call.

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.

A vulnerability in the Mail library affects the q_value_decode and b_value_decode functions, which decode only the first RFC 2047 encoded-word in a string and use an overly greedy pattern to match the charset token. A crafted, malformed encoded-word embedded in an address display name or local part could cause incorrect decoding.

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.

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.

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 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.

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 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, a race condition was fixed in the OA TC6 network driver between reference pointers for TX packets. The issue involves managing two skb pointers for packets enqueued from the network stack.

W QEMU w wersji do 5.1.0 odkryto problem związany z dostępem do pamięci poza przydzielonym zakresem. Błąd ten występuje w procedurze ati_2d_blt() podczas obsługi operacji zapisu MMIO przez funkcję zwrotną ati_mm_write().
