CVE-2026-14671 PostgreSQL refint plan cache type confusion executes arbitrary code

Type confusion in PostgreSQL module "refint" allows an object creator to execute arbitrary code as the operating system user running the database. The fix for this emerged as a non-security bug report, and the fix appear in the git repository with subject "refint: Remove plan cache.", without a C...

python: Python tarfile module: Denial of Service via improper EOF handling in streaming mode

A flaw was found in the Python tarfile module. When processing a specially crafted tar archive opened in 'streaming mode' mode='r|', the module does not properly handle the end-of-file EOF condition. This can cause the tarfile module to enter an infinite loop, leading to a Denial of Service DoS f...

bind: bind9: Potential memory usage beyond configured limits

A DNSSEC validating resolver that is under a random subdomain attack against a DNSSEC-signed zone can suffer from runaway memory usage. The attacker needs to be able to send queries faster than the resolver can perform validation. The increased memory usage can be orders of magnitude beyond the...

bind: bind9: Cache poisoning via label count discrepancy, RRSIG, wildcards

It is possible for an attacker's zone to respond to a query with an RRSIG that has a smaller number of labels than the zone in which the RRSIG is contained. This causes named to produce a wildcard name for a zone that is shorter than the attacker's zone, which can result in cache poisoning. For...

bind: bind9: Incorrect acceptance of NSEC3 records

BIND may accept incorrect child-zone NSEC3 records as valid, which could allow an attacker to forge authenticated NXDOMAIN responses...

bind: bind9: Unexpected exit with NSEC and NSEC3 both present

If a provably insecure domain is covered by both an NSEC and NSEC3 record at the parent, and there exist an RRSIG for only one of these types, then BIND may exit unexpectedly with an assertion while validating this proof...

bind9: bind: Potential wildcard CNAME RPZ policy bypass

An attacker who knows or guesses that a resolver uses RPZ with wildcard CNAME policies can craft query names long enough to trigger a NAMETOOLONG error condition during RPZ processing. This is not handled correctly and may lead to defeating the RPZ rule. It also may lead to an unexpected exit of...

bind: bind9: DNSSEC Validation Bypass via Out-of-Zone NSEC Next Field

The BIND resolver accepts validly-signed NSEC records where the "Next Domain Name" field points outside the signer's zone...
