USN-8678-1: OpenSSL vulnerabilities

It was discovered that OpenSSL incorrectly handled the QUIC server incoming channel queue. A remote attacker could possibly use this issue to cause OpenSSL to use excessive resources, leading to a denial of service. This issue only affected Ubuntu 26.04 LTS. CVE-2026-14456 It was discovered that...

USN-8678-1 openssl vulnerabilities

It was discovered that OpenSSL incorrectly handled the QUIC server incoming channel queue. A remote attacker could possibly use this issue to cause OpenSSL to use excessive resources, leading to a denial of service. This issue only affected Ubuntu 26.04 LTS. CVE-2026-14456 It was discovered that...

CVE-2026-18798

A flaw was found in OpenSSL. A malformed INITIAL packet with an invalid DCID destination connection ID can cause the QUIC server to double free the QRX object. This issue leads to memory corruption, causing the termination of the QUIC server process and resulting in a denial of service. Mitigatio...

CVE-2026-63075

A flaw was found in OpenSSL. The QUIC protocol implementation retains metadata for ACK-only packets for the lifetime of a connection, leading to excessive memory consumption. This allows a peer to repeatedly send ack-eliciting packets while not acknowledging ACK-only responses to cause memory...

Double Free

Overview Affected versions of this package are vulnerable to Double Free in QRX handling during channel creation failure. An attacker can trigger heap corruption and terminate the QUIC server process by sending a malformed INITIAL packet that makes portbindchannel fail after QRX allocation and...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling unbounded resource growth due to osslackmontxpacket in ssl/quic/quicackm.c and txppktcommit in ssl/quic/quictxp.c. A remote peer can exhaust memory by completing a QUIC handshake and...

AZL-97938 CVE-2026-63075 affecting package openssl 3.3.7-4

Issue summary: When OpenSSL processes QUIC traffic from a peer that repeatedly sends ack-eliciting packets while not acknowledging ACK-only responses, the QUIC stack can retain ACK-only packet metadata for the lifetime of the connection. Impact summary: A remote peer that can complete a QUIC...
