github.com/cri-o/cri-o: Fix Bypass for CVE-2022-4318 — /etc/passwd Injection via HOME env

A flaw was found in CRI-O. The fix for a previous vulnerability CVE-2022-4318 was incorrect, allowing it to be bypassed. An attacker capable of setting environment variables on a container can inject a newline character into the HOME environment variable. This issue allows the addition of arbitra...

CVE-2026-87822 t-digest 3.1 through 3.3 Denial of Service via NaN Centroid Means in MergingDigest.fromBytes

t-digest versions 3.1 through 3.3 fail to validate centroid means during deserialization in MergingDigest.fromBytes, allowing attackers to inject NaN values that bypass validation checks. Attackers can craft malicious serialized digests containing NaN centroids that degrade sorting performance fr...

SUSE CVE-2026-18355

A heap buffer overflow flaw was found in the SASL I/O layer of 389 Directory Server 389-ds-base. In sasliostartpacket, the wrapped-record length read from the wire is validated only against an upper bound. A small wire length 0, 1, or 2 produces an encryptedbuffercount below the already-consumed...
