Heap-based Buffer Overflow

An out-of-bounds write flaw was found in grub2's NTFS filesystem driver. This issue may allow an attacker to present a specially crafted NTFS filesystem image, leading to grub's heap metadata corruption. In some circumstances, the attack may also corrupt the UEFI firmware heap metadata. As a result, arbitrary code execution and secure boot protection bypass may be achieved.Show less

A heap-based buffer overflow vulnerability exists in the vpnserver WpcParsePacket() functionality of SoftEther VPN 4.41-9782-beta, 5.01.9674 and 5.02. A specially crafted network packet can lead to arbitrary code execution. An attacker can perform a man-in-the-middle attack to trigger this vulnerability.Show less

A vulnerability was found in Delta Electronics WPLSoft up to 2.51 and classified as problematic. This issue affects some unknown processing of the component Modbus Data Packet Handler. The manipulation leads to heap-based buffer overflow. The exploit has been disclosed to the public and may be used. The associated identifier of this vulnerability is VDB-241583. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.Show less

A heap-based buffer overflow vulnerability was found in coders/tiff.c in ImageMagick. This issue may allow a local attacker to trick the user into opening a specially crafted file, resulting in an application crash and denial of service.Show less

A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted GLIBC_TUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges.Show less

Due to failure in validating the length provided by an attacker-crafted PPD PostScript document, CUPS and libppd are susceptible to a heap-based buffer overflow and possibly code execution. This issue has been fixed in CUPS version 2.4.7, released in September of 2023.Show less

Dell PowerEdge BIOS and Dell Precision BIOS contain a buffer overflow vulnerability. A local malicious user with high privileges could potentially exploit this vulnerability, leading to corrupt memory and potentially escalate privileges.   Show less

A flaw was found in GLib. The GVariant deserialization code is vulnerable to a heap buffer overflow introduced by the fix for CVE-2023-32665. This bug does not affect any released version of GLib, but does affect GLib distributors who followed the guidance of GLib developers to backport the initial fix for CVE-2023-32665.Show less
