A vulnerability was determined in GNU LibreDWG 0.13.4-154-g0b573035. This impacts the function decompress_R2004_section of the file src/decode.c of the component R2004 Section Decompression. Executing a manipulation can lead to heap-based buffer overflow. The attack requires local access. The exploit has been publicly disclosed and may be utilized. Upgrading to version 0.14.8396 will fix this issue. This patch is called 3d0f9fc2eddbd6579c99af3111c37c98f03475d0. You should upgrade the affected component.Show less

A security vulnerability has been detected in SecureAge CatchPulse up to 10.9.3. The affected element is an unknown function in the library saappctl.sys of the component Driver. Such manipulation leads to heap-based buffer overflow. An attack has to be approached locally. The exploit has been disclosed publicly and may be used. Upgrading to version 10.10.0 is sufficient to fix this issue. You should upgrade the affected component. The vendor was contacted early about this disclosure.Show less

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.28.0 on 32-bit builds, FreeRDP clients contain an integer overflow in update_read_delta_points in libfreerdp/core/orders.c when multiplying an attacker-controlled point count by sizeof(DELTA_POINT), allowing a malicious RDP peer to allocate an undersized heap buffer and then write beyond it during initialization. This issue is fixed in version 3.28.0.Show less

osquery is a SQL powered operating system instrumentation, monitoring, and analytics framework. Prior to 5.23.1, on Windows, a local unprivileged attacker can cause a heap buffer out-of-bounds write if there is a query of the authenticode table targeting a maliciously crafted binary, due to publisher information parsing in getOriginalProgramName. If exploited successfully, this could allow a potential local privilege escalation from standard user to SYSTEM. This issue is fixed in version 5.23.1.Show less

osquery is a SQL powered operating system instrumentation, monitoring, and analytics framework. Prior to 5.23.1, on Windows, a local unprivileged attacker can cause a heap buffer out-of-bounds write if there is a query of the processes table targeting a maliciously crafted process, due to unchecked PEB string lengths in process command-line and current-directory reads. If exploited successfully, this could allow a potential local privilege escalation from standard user to SYSTEM. This issue is fixed in version 5.23.1.Show less

A flaw was found in libarchive. This vulnerability allows a remote attacker to trigger a heap overflow by providing a specially crafted tar archive. The issue occurs during the parsing of a PAX extended header containing a malformed SUN.holesdata sparse-file attribute. Successful exploitation could lead to a denial of service, making the system unavailable, or potentially allow for arbitrary code execution, giving the attacker control over the affected system.Show less
