UBUNTU-CVE-2026-58404

Hugo is a static site generator. From v0.162.0 through v0.163.0, the default security.http.urls policy denies requests to loopback, internal, and cloud-metadata IPv4 literals, but the deny rule only matched dotted-decimal notation, so alternate IPv4 encodings of the same addresses, including...

net: golang: Go net package: Denial of Service via long CNAME response in LookupCNAME

A flaw was found in the net package of Go golang, specifically when using the LookupCNAME function with the cgo DNS resolver. A remote attacker could exploit this by providing a very long Canonical Name CNAME response. This can trigger a double-free of C memory, leading to a crash and a Denial of...

CVE-2026-10657

Zephyr's DNS resolver detects mDNS .local queries in dnsresolvenameinternal subsys/net/lib/dns/resolve.c with memcmpstrrchrquery, '.', ".local", 7, which always reads a fixed 7 bytes from the suffix pointer. When the resolved hostname's final label is shorter than 7 bytes e.g. names ending in .or...

io.netty/netty-resolver-dns: Netty has Insufficient Bailiwick Validation for NS Records

A flaw was found in Netty's DnsResolveContext. An attacker controlling an authoritative name server for a subdomain can exploit this vulnerability by providing crafted NS records that are insufficiently validated. This allows the attacker to poison the DNS cache for parent domains, bypassing...

netty-resolver-dns: Netty: Information disclosure and data manipulation due to improper CNAME record validation

A flaw was found in Netty's DnsResolveContext. This vulnerability allows a remote attacker to achieve information disclosure or data manipulation by crafting malicious DNS responses. The flaw occurs because the DnsResolveContext fails to validate the origin bailiwick of CNAME records in DNS...

CVE-2026-58449 txtai - Unauthenticated Remote Code Execution via Unsafe Reflection in API /reindex function Parameter

txtai through 9.10.0, fixed in commit 11b32da, exposes an API /reindex endpoint whose function body parameter is resolved through txtai.util.Resolver, which performs import and getattr on the caller-supplied dotted path with no allowlist. When the API is exposed with no TOKEN configured...
