SUSE CVE-2026-83601

Netdata is an open source observability tool. Prior to 2.10.4, an authenticated child agent can send an oversized DIMENSION SLOT value that str2ullencoded passes to pluginsdrrddimputtoslot in src/plugins.d/pluginsdinternals.h without an upper bound. prdarraycreate in...

vim: Vim: Heap buffer overflow allows arbitrary code execution

A heap buffer overflow in Vim allows a local attacker to cause a denial of service or potentially execute arbitrary code. The flaw is triggered by processing a specially crafted spell file, where the setsofo function fails to reset internal data between sections, leading to an out-of-bounds write...

postgresql: PostgreSQL: Arbitrary code execution via long POSIX timezone abbreviation

A heap buffer overflow flaw was found in the PostgreSQL tochartimestamptz function. An attacker can exploit this by supplying an overly long POSIX timezone abbreviation to execute arbitrary code as the database's operating system user, potentially resulting in complete system compromise...

postgresql: PostgreSQL: Arbitrary code execution via plperl tied hash heap buffer overflow

A flaw was found in PostgreSQL. A heap buffer overflow vulnerability exists in the plperl component when returning a tied hash. This allows a function owner to execute arbitrary code as the operating system user running the database by providing a specially crafted function body. This could lead ...

unbound: Unbound: Heap buffer overflow via malicious DNSSEC response

A flaw was found in Unbound. This vulnerability allows a remote attacker to cause a heap buffer overflow during the processing of DNSSEC responses. By sending a specially crafted DNSSEC response, a malicious server or an attacker tampering with network traffic can trigger this flaw. This could le...

unbound: Unbound: Heap buffer overflow and possible Remote Code Execution when digesting DNSKEY

A flaw was found in Unbound's DNSSEC validator. A remote attacker can exploit this vulnerability by controlling a malicious zone and sending a specially crafted DNSKEY record. This can lead to a heap buffer overflow, potentially resulting in a denial of service or remote code execution...
