CVE-2026-2474 1 Ddick 2 Crypt::urandom, Crypt\ 2026-03-04 7.5 High
Crypt::URandom versions from 0.41 before 0.55 for Perl is vulnerable to a heap buffer overflow in the XS function crypt_urandom_getrandom(). The function does not validate that the length parameter is non-negative. If a negative value (e.g. -1) is supplied, the expression length + 1u causes an integer wraparound, resulting in a zero-byte allocation. The subsequent call to getrandom(data, length, GRND_NONBLOCK) passes the original negative value, which is implicitly converted to a large unsigned value (typically SIZE_MAX). This can result in writes beyond the allocated buffer, leading to heap memory corruption and application crash (denial of service). In common usage, the length argument is typically hardcoded by the caller, which reduces the likelihood of attacker-controlled exploitation. Applications that pass untrusted input to this parameter may be affected.
CVE-2026-2597 1 Leont 2 Crypt::sysrandom::xs, Crypt\ 2026-03-03 7.5 High
Crypt::SysRandom::XS versions before 0.010 for Perl is vulnerable to a heap buffer overflow in the XS function random_bytes(). The function does not validate that the length parameter is non-negative. If a negative value (e.g. -1) is supplied, the expression length + 1u causes an integer wraparound, resulting in a zero-byte allocation. The subsequent call to chosen random function (e.g. getrandom) passes the original negative value, which is implicitly converted to a large unsigned value (typically SIZE_MAX). This can result in writes beyond the allocated buffer, leading to heap memory corruption and application crash (denial of service). In common usage, the length argument is typically hardcoded by the caller, which reduces the likelihood of attacker-controlled exploitation. Applications that pass untrusted input to this parameter may be affected.
CVE-2026-28418 1 Vim 1 Vim 2026-03-03 4.4 Medium
Vim is an open source, command line text editor. Prior to version 9.2.0074, a heap-based buffer overflow out-of-bounds read exists in Vim's Emacs-style tags file parsing logic. When processing a malformed tags file, Vim can be tricked into reading up to 7 bytes beyond the allocated memory boundary. Version 9.2.0074 fixes the issue.
CVE-2026-3195 1 Qemu 1 Qemu 2026-03-03 7.4 High
A flaw was found in QEMU. When reading input audio in the virtio-snd device input callback, the `virtio_snd_pcm_in_cb` function did not check whether the iov could fit the data buffer, potentially leading to a heap out-of-bounds write. This issue exists due to an incomplete fix for CVE-2024-7730.
CVE-2017-5225 1 Libtiff 1 Libtiff 2026-03-03 8.8 High
LibTIFF version 4.0.7 is vulnerable to a heap buffer overflow in the tools/tiffcp resulting in DoS or code execution via a crafted BitsPerSample value.
CVE-2026-3407 1 Yosyshq 1 Yosys 2026-03-02 3.3 Low
A vulnerability was determined in YosysHQ yosys up to 0.62. This affects the function Yosys::RTLIL::Const::set of the file kernel/rtlil.h of the component BLIF File Parser. This manipulation causes heap-based buffer overflow. It is possible to launch the attack on the local host. The exploit has been publicly disclosed and may be utilized. Applying a patch is the recommended action to fix this issue. It appears that the issue is not reproducible all the time.
CVE-2026-3281 1 Libvips 1 Libvips 2026-03-02 5.3 Medium
A vulnerability was detected in libvips 8.19.0. This affects the function vips_bandrank_build of the file libvips/conversion/bandrank.c. Performing a manipulation of the argument index results in heap-based buffer overflow. The attack must be initiated from a local position. The exploit is now public and may be used. The patch is named fd28c5463697712cb0ab116a2c55e4f4d92c4088. It is suggested to install a patch to address this issue.
CVE-2026-27168 2 Happyseafox, Sail 2 Sail, Sail 2026-03-02 8.8 High
SAIL is a cross-platform library for loading and saving images with support for animation, metadata, and ICC profiles. All versions are vulnerable to Heap-based Buffer Overflow through the XWD parser's use of the bytes_per_line value. The value os read directly from the file as the read size in io->strict_read(), and is never compared to the actual size of the destination buffer. An attacker can provide an XWD file with an arbitrarily large bytes_per_line, causing a massive write operation beyond the buffer heap allocated for the image pixels. The issue did not have a fix at the time of publication.
CVE-2023-52356 2 Libtiff, Redhat 4 Libtiff, Ai Inference Server, Discovery and 1 more 2026-02-27 7.5 High
A segment fault (SEGV) flaw was found in libtiff that could be triggered by passing a crafted tiff file to the TIFFReadRGBATileExt() API. This flaw allows a remote attacker to cause a heap-buffer overflow, leading to a denial of service.
CVE-2026-23750 1 Golioth 1 Pouch 2026-02-27 8.1 High
Golioth Pouch version 0.1.0, prior to commit 1b2219a1, contains a heap-based buffer overflow in BLE GATT server certificate handling. server_cert_write() allocates a heap buffer of size CONFIG_POUCH_SERVER_CERT_MAX_LEN when receiving the first fragment, then appends subsequent fragments using memcpy() without verifying that sufficient capacity remains. An adjacent BLE client can send unauthenticated fragments whose combined size exceeds the allocated buffer, causing a heap overflow and crash; integrity impact is also possible due to memory corruption.
CVE-2026-27799 2 Dlemstra, Imagemagick 2 Magick.net, Imagemagick 2026-02-27 4 Medium
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, a heap buffer over-read vulnerability exists in the DJVU image format handler. The vulnerability occurs due to integer truncation when calculating the stride (row size) for pixel buffer allocation. The stride calculation overflows a 32-bit signed integer, resulting in an out-of-bounds memory reads. Versions 7.1.2-15 and 6.9.13-40 contain a patch.
