USN-8719-1

It was discovered that APR-util incorrectly performed password hash comparisons in a way that was not constant-time. An attacker could possibly use this issue to obtain sensitive information. (CVE-2025-49506)

It was discovered that APR-util incorrectly handled recursive XML element quoting. An attacker could possibly use this issue to cause applications using APR-util to crash, resulting in a denial of service. (CVE-2026-32327)

It was discovered that the APR-util Redis client incorrectly handled certain network data, resulting in a heap-based buffer overflow. A remote attacker could possibly use this issue to cause APR-util applications to crash or execute arbitrary code. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, and Ubuntu 26.04 LTS. (CVE-2026-34501)

It was discovered that the APR-util memcached client incorrectly handled certain network data, resulting in a heap-based buffer overflow. A remote attacker could possibly use this issue to cause APR-util applications to crash or execute arbitrary code. (CVE-2026-34502)
