389-ds-base: 389-ds-base: heap buffer overflow via SASL wrapped-record length lower-bound underflow in sasl_io_start_packet()

A heap buffer overflow flaw was found in the SASL I/O layer of 389 Directory Server 389-ds-base. In sasliostartpacket, the wrapped-record length read from the wire is validated only against an upper bound. A small wire length 0, 1, or 2 produces an encryptedbuffercount below the already-consumed...

389-ds-base: 389-ds-base: Command injection via unescaped LDAP DN in Cockpit 389 Console LDAP editor

A flaw was found in 389-ds-base. The Cockpit 389 Console's LDAP editor constructs an ldapsearch command by embedding an LDAP entry's distinguished name DN into a shell command string without proper escaping. An LDAP user with delegated privileges to create or rename directory entries could craft ...

389-ds-base: 389-ds-base: SASL PLAIN authentication allows privilege escalation to Directory Manager via stale identity in Cyrus SASL auxiliary property

A flaw was found in 389 Directory Server. During SASL PLAIN authentication, a stale identity carried in a Cyrus SASL auxiliary property from a prior failed bind attempt can be installed on a connection following a subsequent, unrelated successful bind, regardless of which SASL mechanism completes...

389-ds-base: 389-ds: anonymous LDAP client can defeat SELFDN ACI bind-rule checks via empty bind DN

A flaw was found in 389 Directory Server. The SELFDN ACI bind-rule evaluator incorrectly matches an anonymous LDAP client's empty bind DN against an empty stored attribute value, allowing an unauthenticated client to satisfy access control checks intended to require a matching authenticated...

389-ds-base: 389-ds: anonymous LDAP client can defeat SELFDN ACI bind-rule checks via empty bind DN

A flaw was found in 389 Directory Server. The SELFDN ACI bind-rule evaluator incorrectly matches an anonymous LDAP client's empty bind DN against an empty stored attribute value, allowing an unauthenticated client to satisfy access control checks intended to require a matching authenticated...

389-ds-base: 389-ds-base: pre-authentication NULL pointer dereference via paged results and USE_ONE_BACKEND control in op_shared_search

A flaw was found in 389 Directory Server. A missing NULL pointer check in the paged results handling of opsharedsearch allows an unauthenticated remote attacker to crash the LDAP server by sending a crafted sequence of search requests using the USEONEBACKEND control, resulting in denial of servic...

Updated tor packages fix security vulnerabilities

An out-of-bounds write when parsing a consensus or detached signature with unexpected signature digest type CVE-2026-77642. A NULL write after free when sending a CONFLUXSWITCH cell fails, resulting in a crash CVE-2026-77641. An infinite loop when decompressing a truncated zlib/gzip stream with...

Updated freerdp packages fix security vulnerabilities

Updated packages bring lot of security fixes. Please see the links for additional information...

kernel: nvmet-rdma: handle inline data with a nonzero offset

A flaw was found in the nvmet-rdma component of the Linux kernel. This vulnerability arises from incorrect handling of inline data with a non-zero offset, which can lead to an integer underflow. An attacker could exploit this to cause the system to read beyond its allocated memory, potentially...

kernel: netfilter: conntrack: remove sprintf usage

A flaw was found in the Linux kernel's netfilter conntrack module. This vulnerability arises from the use of sprintf and insufficient buffer sizing in the manglecontentlen function, which can lead to a stack-out-of-bounds write. An attacker could potentially exploit this memory corruption issue t...

kernel: net: bridge: stop fast-leave after deleting a port group

A flaw was found in the Linux kernel's network bridge module. When handling multicast fast-leave, a vulnerability exists where the system may attempt to access a port group after it has been deleted. This can occur if multicast-to-unicast was previously enabled and then disabled, leading to a sta...

kernel: crypto: pcrypt - Fix handling of MAY_BACKLOG requests

A flaw was found in the Linux kernel's pcrypt component. This vulnerability involves how the system handles certain requests, specifically MAYBACKLOG requests, which can indicate a temporary busy state. If not properly managed, the system's processing of these requests could lead to resource...

kernel: rhashtable: clear stale iter->p on table restart

A flaw was found in the Linux kernel. This vulnerability, known as a use-after-free, occurs in the rhashtable component when the system improperly handles hash table restarts. An attacker could potentially exploit this by causing the system to access memory that has already been released, which m...

kernel: netfilter: synproxy: refresh tcphdr after skb_ensure_writable

A flaw was found in the Linux kernel's netfilter synproxy module. When handling TCP timestamp options, a stale pointer can be used after memory reallocation. This can result in memory corruption, where data is written to a freed memory area, or lead to packets being sent with an incorrect checksu...

kernel: smb: client: validate DFS referral PathConsumed

A flaw was found in the Linux kernel's Server Message Block SMB client. A remote attacker could send a specially crafted SMB response containing a malformed Distributed File System DFS referral. This could cause the PathConsumed value to exceed the search name length, leading to an out-of-bounds...
