CVE-2026-42617 Alta · 7.1 CWE-122 07/10/2026

Heap-based Buffer Overflow em Tuxera Ntfs-3g

In NTFS-3G before 2026.7.7, a heap buffer overflow exists in ntfs_ir_to_ib() in index.c that allows an attacker to corrupt heap memory in the SUID-root ntfs-3g binary by crafting a malicious NTFS image. The overflow is triggered by extending a directory, e.g., by creating a file.

CVE-2026-106547 Alta · 8.5 CWE-122 06/10/2026

HDF5 heap buffer overflow in H5VM_array_fill via crafted fill-value metadata

A heap-based buffer overflow in H5VM_array_fill() in src/H5VM.c in HDF5 before 2.2.0 lets a remote attacker cause an application crash and possibly execute arbitrary code with a crafted HDF5 file. When a dataset's unallocated chunks are read, H5D__fill_init() fills the fill-value buffer from datatype and dataspace metadata in the file. If that metadata is inconsistent with the buffer's allocated size, the write goes past the end of the buffer. The attacker can control the content written through the fill value stored in the file.

CVE-2026-105842 Média · 6.4 CWE-122 06/10/2026

lrzsz before 0.13.0 Heap Buffer Overflow via lrz procheader() Pathname

lrzsz before 0.13.0 contains a heap-based buffer overflow vulnerability in procheader() of the lrz receive utility when copying overlong sender-supplied filenames into Pathname. Malicious ZMODEM senders can supply filenames up to 8192 bytes, overflowing the buffer via sprintf() in pipe mode or strcpy() to corrupt heap memory and crash lrz.

CVE-2026-75818 Baixa · 1.8 CWE-122 06/10/2026

Heap Buffer Overflow in GNU Aspell's prezip utility

GNU Aspell prezip-bin contains a heap-based buffer overflow vulnerability in the decompressor in prog/prezip.c. The decompressor does not properly check buffer space, so a crafted compressed file can cause out-of-bounds read and write operations on the heap. An attacker who convinces a user to process a malicious compressed file with prezip-bin can trigger memory corruption, leading to a processs crash. This issue was fixed in commit 15b188437f9e0192d4ac4472ad66a4e2f62a782f which will be released in version 0.60.8.3.

Apache Thrift: C++ THttpTransport grows its line buffer without bound

Allocation of resources without limits or throttling, Integer overflow or wraparound, Heap-based buffer overflow vulnerability in Apache Thrift. This issue affects Apache Thrift: before 0.25.0. Users are recommended to upgrade to version 0.25.0, which fixes the issue.

CVE-2026-91135 Crítica · 9.2 CWE-122 02/10/2026

Apache Thrift: C++ `THeaderTransport::transform()` heap buffer overflow (write direction)

Heap-based buffer overflow vulnerability in Apache Thrift C++ THeaderTransport. When an application enables the ZLIB transform for the frames it sends, THeaderTransport::transform() copies the compressed frame into the write buffer without making sure it fits. Data that does not compress, such as content a remote peer supplied, grows under compression, so the copy writes past the end of the heap buffer by an amount that grows with the size of the frame, and for large frames it also reads past the end of the transform buffer. This issue affects Apache Thrift: before 0.25.0. Users are recommended to upgrade to version 0.25.0, which fixes the issue.

CVE-2026-14316 Alta · 8.1 CWE-122 01/10/2026

Heap buffer overflow in boks_sshd revoked-key error handling

The revoked-key error path builds a human-readable failure reason using sprintf() into a heap buffer. The allocated buffer is too small for the final formatted message. When sprintf() writes the full message, it can write past the end of the heap allocation.

Heap-based Buffer Overflow em Esnet Iperf3

iperf3 3.20–3.21 (esnet/iperf) has a pre-auth heap buffer overflow in decrypt_rsa_message(): a 256-byte RSA buffer is BIO_read with the attacker-controlled ciphertext length (guard warns only), so an unauthenticated client overflows the heap via an oversized authtoken; fixed in 3.22

CVE-2026-103242 Alta · 7.1 CWE-122 30/09/2026

Rpm: heap-based buffer overflow write in hex2binv() via a mistyped rpmtag_filesignatures header tag

A heap-based buffer overflow flaw was found in rpm. RPMTAG_FILESIGNATURES in a crafted, unsigned RPM package's main header is declared with the wrong header type, causing hex2binv() to allocate a one-byte buffer and then write the tag's attacker-controlled, hex-decoded content — of attacker-chosen length — past the end of that allocation. This is reachable via rpm2cpio, rpm2archive, and rpm -qlvp on an untrusted package.

Heap-Based Buffer Overflow in TeamViewer Session Recording Playback Leads to Remote Code Execution

TeamViewer Full Client and Host for Linux and macOS prior version 15.82 contain a heap-based buffer overflow vulnerability in the processing of .tvs session recording files.
