OESA-2026-2635 libsolv security update

A free package dependency solver using a satisfiability algorithm. The library is based on two major, but independent, blocks: Security Fixes: A flaw was found in libsolv. A stack-based buffer overflow vulnerability exists in the PGP verification component due to incorrect length handling when...

Important: libsolv

Issue Overview: A flaw was found in libsolv. A stack-based buffer overflow vulnerability exists in the PGP verification component due to incorrect length handling when copying EdDSA 's' MPI into a stack buffer. A remote attacker could craft a malicious Ed25519 PGP signature with mismatched MPI...

TencentOS Server 4: libsolv (TSSA-2026:0423)

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2026:0423 advisory. Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:...

Astra Linux – Vulnerability in Node-Elliptic

The verify function in lib/elliptic/eddsa/index.js within the Elliptic package, as of version 6.5.6 for Node.js, omits the validation of the condition “sig.S.gtesig.eddsa.curve.n || sig.S.isNeg”...

Improper Certificate Validation

Overview wolfssl is a None Affected versions of this package are vulnerable to Improper Certificate Validation. due to missing hash/digest size and OID checks in the certificate verification process. An attacker can bypass signature verification by providing digests smaller than allowed when...

UBUNTU-CVE-2026-5194

Missing hash/digest size and OID checks allow digests smaller than allowed when verifying ECDSA certificates, or smaller than is appropriate for the relevant key type, to be accepted by signature verification functions. This could lead to reduced security of ECDSA certificate-based authentication...

CVE-2026-5194

The CVE-2026-5194 issue concerns wolfSSL’s ECDSA certificate verification: missing hash/digest size and OID checks may allow digests smaller than allowed for the given key type to pass verification when EdDSA or ML-DSA is enabled. This could reduce security of ECDSA certificate-based authenticati...
