UBUNTU-CVE-2026-73198

A flaw was found in FreeIPA. A remote, unauthenticated attacker can exploit a vulnerability in the /ipa/i18nmessages endpoint by sending an arbitrarily large request body. This can cause the service to consume excessive memory, leading to memory exhaustion, degraded responsiveness, and a denial o...

UBUNTU-CVE-2026-13097

A privilege escalation flaw was found in FreeIPA. The uniqueness constraint enforced on Kerberos principal name attributes in the 389-ds directory server does not properly account for equivalent representations of the same principal name, allowing a user with sufficient LDAP write privileges to...

UBUNTU-CVE-2026-73196

A flaw was found in FreeIPA. A low-privilege authenticated user can exploit this vulnerability by submitting an oversized One-Time Password OTP key value. This oversized key is then decoded and re-encoded without proper size limits, consuming excessive CPU and memory resources. This can lead to a...

UBUNTU-CVE-2026-11861

A flaw was found in FreeIPA. When a trust relationship is configured between FreeIPA and Active Directory, Active Directory users can bypass authentication for FreeIPA services, including the portal, SMB server, and LDAP directory. This is possible by impersonating a client name in the Ticket...

UBUNTU-CVE-2026-18917

A flaw was found in libvirt. An unprivileged local user could exploit an integer overflow vulnerability in the NodeGetFreePages RPC handler. This flaw allows crafted values to bypass a size check, leading to an undersized memory buffer. Subsequently, real NUMA node data can overwrite this buffer...

UBUNTU-CVE-2026-77014

A flaw was found in libsoup's SoupServer HTTP Range header processing. The sortranges comparator in soup-message-headers.c truncates a 64-bit subtraction result to 32-bit int, flipping the sign for range offsets differing by more than INTMAX. This causes silent omission of requested byte ranges...

UBUNTU-CVE-2026-76956
