A flaw was found in GLib. A state confusion issue exists in gdbusnodeinfonewforxml in the gio/gdbusintrospection.c file when processing malformed D-Bus introspection XML, specifically with a node element nested within other elements like method, signal, property or arg. This issue can cause an...

CVE-2026-58058

A flaw was found in Nmap. A remote attacker or a scanned target can send a specially crafted IPv6 response with a truncated extension header. This can lead to an integer underflow, causing out-of-bounds reads and a denial of service DoS due to a crash during raw IPv6 scans. Mitigation Mitigation...

gnutls: GnuTLS: Denial of Service via DTLS zero-length fragment

A flaw in GnuTLS DTLS handshake parsing allows malformed fragments with zero length and non-zero offset, leading to an integer underflow during reassembly and resulting in an out-of-bounds read. This issue is remotely exploitable and may cause information disclosure or denial of service...

CVE-2026-58058 Nmap - Integer Underflow in IPv6 Extension Header Parsing

Nmap through 7.99 does not keep the IPv6 extension-header walk within the captured packet in ipv6getdataprimitive libnetutil/netutil.cc, so the pointer advances past the buffer and the remaining-length computation underflows to a large value. A scanned target or on-path attacker returning a craft...

CVE-2026-58058

CVE-2026-58058 : Nmap up to 7.99 is affected by an integer underflow in IPv6 extension-header parsing (ipv6_get_data_primitive in libnetutil/netutil.cc). A crafted or truncated IPv6 extension header returned by a scanned target or on-path attacker can cause the remaining-length to underflow to a ...
