Allocation of resources without limits or throttling in the HTTP/2 HPACK decoder in Apache HttpComponents Core (5.4.2 and earlier, 5.5-beta1 and earlier) allows an remote attacker to cause a denial of service through memory exhaustion by sending oversized compressed header blocks before the HTTP/2 SETTINGS acknowledgement causes the configured header list size limit to be applied.

The versions of Oracle Database Server installed on the remote host are affected by multiple vulnerabilities as referenced in the October 2026 CPU advisory.

  - Vulnerability in the RDBMS (OpenSSL) component of Oracle Database Server. Supported versions that are     affected are 19.3-19.32 and 23.4.0-23.26.3. Easily exploitable vulnerability allows unauthenticated     attacker with network access via TLS to compromise RDBMS (OpenSSL). Successful attacks of this     vulnerability can result in takeover of RDBMS (OpenSSL). (CVE-2026-14456, CVE-2026-14457, CVE-2026-18798,     CVE-2026-54874, CVE-2026-63072, CVE-2026-63074, CVE-2026-63075, CVE-2026-63076, CVE-2026-75803)

  - Vulnerability in the RDBMS component of Oracle Database Server. Supported versions that are affected are     23.4.0-23.26.3. Easily exploitable vulnerability allows low privileged attacker having DBMS_VECTOR     privilege with network access via Oracle Net to compromise RDBMS. Successful attacks of this vulnerability     can result in takeover of RDBMS. (CVE-2026-91499)

  - Vulnerability in the Oracle OLAP component of Oracle Database Server. Supported versions that are affected     are 19.3-19.32, 21.3-21.23 and 23.4.0-23.26.3. Easily exploitable vulnerability allows low privileged     attacker having DBMS_AW privilege with network access via Oracle Net to compromise Oracle OLAP. Successful     attacks of this vulnerability can result in takeover of Oracle OLAP. (CVE-2026-91563)

  - Vulnerability in the RDBMS (Micronaut) component of Oracle Database Server. Supported versions that are     affected are 19.3-19.32 and 23.4.0-23.26.3. Easily exploitable vulnerability allows unauthenticated     attacker with network access via HTTP to compromise RDBMS (Micronaut). Successful attacks of this     vulnerability can result in unauthorized creation, deletion or modification access to critical data or all     RDBMS (Micronaut) accessible data as well as unauthorized read access to a subset of RDBMS (Micronaut)     accessible data. (CVE-2026-89044, CVE-2026-93492, CVE-2026-93493, CVE-2026-93494, CVE-2026-93560,     CVE-2026-93561, CVE-2026-93563, CVE-2026-93564, CVE-2026-93565, CVE-2026-93566, CVE-2026-93567,     CVE-2026-93568, CVE-2026-93569, CVE-2026-93572, CVE-2026-93573, CVE-2026-93574, CVE-2026-93575,     CVE-2026-93576, CVE-2026-93578, CVE-2026-93579)

  - Vulnerability in the VPD component of Oracle Database Server. Supported versions that are affected are     19.3-19.32, 21.3-21.23 and 23.4.0-23.26.3. Easily exploitable vulnerability allows low privileged attacker     having Create Table privilege with network access via Oracle Net to compromise VPD. Successful attacks of     this vulnerability can result in unauthorized creation, deletion or modification access to critical data     or all VPD accessible data as well as unauthorized access to critical data or complete access to all VPD     accessible data. (CVE-2026-91503)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of Oracle Business Process Management Suite installed on the remote host is affected by multiple vulnerabilities, as referenced in the October 2026 CPU advisory:

  - Vulnerability in the Oracle Business Process Management Suite product of Oracle Fusion Middleware     (component: Human Workflow). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.0.0. Easily     exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise     Oracle Business Process Management Suite. Successful attacks of this vulnerability can result in     takeover of Oracle Business Process Management Suite. (CVE-2026-91220)

  - Vulnerability in the Oracle Business Process Management Suite product of Oracle Fusion Middleware     (component: Human workflow 11g+ (Apache Mina)). Supported versions that are affected are 12.2.1.4.0 and     14.1.2.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via     HTTP to compromise Oracle Business Process Management Suite. Successful attacks of this vulnerability     can result in takeover of Oracle Business Process Management Suite. (CVE-2026-47065)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Allocation of resources without limits or throttling in the HTTP/2 HPACK decoder in Apache HttpComponents
    Core (5.4.2 and earlier, 5.5-beta1 and earlier) allows an remote attacker to cause a denial of service
    through memory exhaustion by sending oversized compressed header blocks before the HTTP/2 SETTINGS
    acknowledgement causes the configured header list size limit to be applied. (CVE-2026-54428)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Allocation of resources without limits or throttling in the HTTP/2 HPACK decoder in Apache HttpComponents     Core (5.4.2 and earlier, 5.5-beta1 and earlier) allows an remote attacker to cause a denial of service     through memory exhaustion by sending oversized compressed header blocks before the HTTP/2 SETTINGS     acknowledgement causes the configured header list size limit to be applied.
