rsyslog: rsyslog: Denial of service via heap buffer overflow in RainerScript replace() function

A flaw was found in rsyslog. An unauthenticated remote attacker can trigger a heap buffer overflow in the RainerScript replace function by sending specially crafted syslog messages. This vulnerability arises from an incorrect buffer size calculation during string replacement, causing memory...

CVE-2026-109279 ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 Heap Buffer Overflow via Concurrent Security Policy Access

ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 lacks proper synchronization when the security policy is accessed, so simultaneous reads and writes of the policy by multiple threads trigger a race condition that causes a heap buffer over-write. An attacker able to induce concurrent security...

CVE-2026-109279

ImageMagick versions before 6.9.13-57 and 7.x before 7.1.2-32 are vulnerable to a heap buffer overflow due to a lack of proper synchronization when accessing the security policy. Simultaneous reads and writes of the policy by multiple threads trigger a race condition (CWE-362). An attacker capabl...

CVE-2026-109256

FreeRDP versions 3.10.0 through 3.32.2 are vulnerable to a heap buffer overflow within the WinPR png_write_data callback. The root cause is a failure to handle a realloc failure , which allows a malicious RDP clipboard peer to trigger an out-of-bounds memcpy by supplying a large CF_DIB image duri...

EUVD-2026-97700

FreeRDP 3.10.0 through 3.32.2 contains a heap buffer overflow in the WinPR pngwritedata callback that writes past the buffer after a realloc failure. A malicious RDP clipboard peer can supply a large CFDIB image that triggers out-of-bounds memcpy during PNG conversion, causing a client crash...
