CVE-2026-56416 Possible heap buffer overflow when validator canonicalizes RDATA that contains domain name

In NLnet Labs Unbound up to and including version 1.25.1, when the validator builds the canonical RDATA form for an RRSIG-covered PX/RP/MINFO/SOA RRset, it computes the address of the second embedded domain name as 'datstart + dnamevaliddatstart, ...' and passes it straight to 'querydnametolower'...

CVE-2026-46582

In NLnet Labs Unbound 1.6.0 up to and including 1.25.1, a replay of a wildcard rrset as another piece of data, could be briefly considered DNSSEC secure based only on the RRSIG validation and stored into cache, before later validation treats it as bogus based on NSEC validation. When the resolvin...

CVE-2026-44690

The CVE-2026-44690 entry concerns NLnet Labs Unbound versions 1.7.0 through 1.25.1 where insufficient validation of the RRSIG.Labels field combined with premature cache writes during RFC 8198 aggressive NSEC processing enables cache poisoning. A malicious actor controlling a single delegated zone...

CVE-2026-44690 Cross-zone wildcard cache poisoning via RRSIG.labels manipulation

In NLnet Labs Unbound 1.7.0 up to and including 1.25.1, insufficient validation of the RRSIG.Labels field combined with premature cache writes during RFC 8198 aggressive NSEC processing leads to cache poisoning that permits a malicious actor controlling a single delegated zone to poison arbitrary...

glibc: glibc: Out-of-bounds write via TSIG record processing

A flaw was found in glibc, the GNU C Library. Specifically, deprecated functions responsible for printing TSIG Transaction Signature records fail to properly manage memory buffers. This oversight can lead to an out-of-bounds write when processing specially crafted TSIG records. An attacker could...

bind: bind9: Unnecessary validation of DNSSEC signed records

The issue is a resource exhaustion vulnerability associated with DNSSEC validation. BIND always validates all RRSIG records in an answer, even if they are not strictly needed. A query to an authoritative server/zone which returns many valid but superfluous RRSIG records causes the validator to...

CVE-2026-47121

Sparkle is a software update framework for macOS. Prior to version 2.9.2, Autoupdate/SUBinaryDeltaApply.m enforces relativePath.pathComponents containsObject:@".." and rejects writes whose immediate parent directory IS itself a symbolic link, but does not detect symlinks deeper in the relative...

CVE-2026-47121

Sparkle vulnerability CVE-2026-47121 (affecting macOS AutoUpdate) arises from a defense-in-depth gap in delta application. An archive item can create a symlink in the destination tree and a subsequent file write may traverse the symlink path, allowing writes outside the intended destination when ...

Sparkle is a software update framework for macOS. Prior to version 2.9.2, Autoupdate/SUBinaryDeltaApply.m enforces relativePath.pathComponents containsObject:@".." and rejects writes whose immediate parent directory IS itself a symbolic link, but does not detect symlinks deeper in the relative...

glibc: glibc: Application crash or uninitialized memory read via crafted DNS response

A flaw was found in glibc GNU C Library. The deprecated functions nsprintrrf, nsprintrr, and fpnquery do not properly validate the length of RDATA Resource Record Data in a DNS Domain Name System response when processing specific record types like LOC, CERT, TKEY, or TSIG. A remote attacker could...

SUSE CVE-2026-9537

Mojo::JWT versions before 1.02 for Perl verify HMAC signatures with a non-constant-time string comparison. The decode method compares the supplied signature to the recomputed HMAC with Perl's eq operator, which stops at the first differing byte, so the comparison time varies with the number of...

Improper Verification of Cryptographic Signature
