CVE-2026-81928

A flaw was found in Net::DNS versions before 1.57 for Perl. An attacker can cause a denial of service DoS by sending a specially crafted DNS message with a misplaced Transaction Signature TSIG record. When a system using Net::DNS, such as a forwarder or proxy, attempts to re-encode this message, ...

encoding/asn1: golang: Go encoding/asn1: Denial of Service via excessive recursion in Unmarshal

A flaw was found in the encoding/asn1 package in Go. An attacker could provide a specially crafted, deeply-nested Abstract Syntax Notation One ASN.1 structure, leading to excessive recursion during the Unmarshal operation. This could result in stack exhaustion and a Denial of Service DoS conditio...

encoding/xml: golang: Go: Denial of Service via XML decoding recursion depth issue

A flaw was found in the encoding/xml package of Go. The DecodeElement function failed to correctly track recursion depth, which could lead to stack exhaustion. A remote attacker could exploit this vulnerability by providing a specially crafted XML input, resulting in a Denial of Service DoS for t...
