CVE-2026-44041 UltraVNC vncWc2Mb calls wcslen() before validating that the wide string is NUL-terminated

UltraVNC through 1.8.2.2 contains an out-of-bounds read in the wide-string to multibyte conversion helper. In rfb/dh.cpp:204, the vncWc2Mb function passes a caller-supplied WCHAR pointer to wcslen before any bounds check. If the caller provides a wide-character buffer that is not properly...

CVE-2026-7383

The CVE concerns OpenSSL’s ASN1 mbstring handling (functions ASN1_mbstring_copy() and ASN1_mbstring_ncopy()). A signed integer overflow in sizing the destination buffer for Unicode output can cause a heap buffer overflow, potentially crashing a process or enabling attacker-controlled code executi...

CVE-2026-7383 Possible Heap Buffer Overflow in ASN.1 Multibyte String Conversion

Issue summary: A signed integer overflow when sizing the destination buffer for Unicode output in ASN1mbstringncopy can lead to a heap buffer overflow. Impact summary: A heap buffer overflow may lead to a crash or possibly attacker controlled code execution or other undefined behaviour. In...

Astra Linux – Vulnerability in unzip

A flaw was discovered in Unzip. The vulnerability occurs during the conversion of a wide string to a local string, resulting in an out-of-bound write operation on the heap. This flaw allows an attacker to submit a specially crafted zip file, causing a crash or code execution...
