AT_SECURE program buffer overflow via $ORIGIN processing

A stack-based buffer overflow in the dynamic loader (ld.so) of the GNU C Library (glibc) versions 2.14 through 2.44 allows a local attacker to crash or corrupt the memory of setuid/setgid (AT_SECURE) programs. When such a program's DT_RPATH or DT_RUNPATH begins with $ORIGIN and is followed by NUL or '/' the loader both reads past the end of the path buffer and writes past the end of a stack-allocated internal buffer. The corrupted loader stack can lead to a loader crash (denial of service) and limited disclosure of process memory.

openstack-octavia: octavia: HAProxy configuration injection via L7 policy redirect_url and redirect_prefix

In OpenStack Octavia before 18.0.1, the Amphora provider driver did not reject control characters in the L7 policy redirect_url and redirect_prefix fields. The RFC 3986 URL validator percent-encodes control characters before validating, and thus newlines passed structural checks, but Octavia stored and wrote the raw unencoded value directly into the HAProxy configuration generated on the amphora. An authenticated project member who owns a load balancer can therefore inject arbitrary HAProxy directives through a REDIRECT_TO_URL L7 policy. Only deployments using the Amphora provider are affected.

Keyfactor SignServer Log Disclosure of Sensitive File Content via PKCS11CryptoToken

An issue was discovered in Keyfactor SignServer before 7.6.0. The attribute ATTRIBUTESFILE in PKCS11CryptoToken can be set to a readable file but not an accepted file (i.e., recognized with attributes). In this case, an error is thrown which - together with the error - also prints the content of the file to the application server log. This gives a user that has both SignServer admin access and access to read the output of the server log (i.e., if remote syslog shipping is configured), the possibility to read the content of files accessible by the local user JBoss.

wpa_supplicant: wpa_supplicant: Security bypass via missing PMKSA validation

An issue in wpa_supplicant all versions before v.2.12 allows a local attacker to bypass proper network context and AKMP matching for PMKSA caching via missing validation in the driver based PMKSA selection path in wpa.c

exim: gnutls: Exim: Use-after-free vulnerability in GnuTLS TLS settings leading to denial of service

Exim before 4.100.1, when certain non-default TLS settings are used with GnuTLS, has a use-after-free.

OpenStack Blazar Lease API Authorization Bypass Enables Authenticated Lease Modification

In OpenStack Blazar before 17.0.1, the V2 lease API does not enforce object-level authorization on its update and delete operations (PUT /v2/leases/{lease_id} and DELETE /v2/leases/{lease_id}). The policy authorize() wrapper attempts to load the target lease to build the authorization target from its owner, but it looks up the lease under the keyword "lease_id" whereas the controller methods name the parameter "id" (and the wsme_pecan.wsexpose wrapper delivers it positionally). The lookup returns None, and thus authorization falls back to the requesting user's own project_id/user_id instead of the target lease owner. Any authenticated user who knows a lease ID can therefore modify or delete leases belonging to other users and projects, bypassing the intended ownership check.

AT_SECURE programs may load attacker-controlled code via $ORIGIN

A time-of-check to time-of-use (TOCTOU) race condition in the dynamic loader (ld.so) of the GNU C Library (glibc) versions 2.14 through 2.44 allows a local attacker to escalate privileges. When expanding $ORIGIN in DT_RPATH for setuid/setgid (AT_SECURE) programs, glibc validates the lexically normalized search path against the trusted directories but then opens the raw, un-normalized path. On systems where the Linux fs.protected_hardlinks sysctl is disabled, a local attacker who hard-links such a program into an attacker-controlled directory and wins a race to replace an intermediate path component with a symbolic link can direct the loader outside the trusted directory, causing it to load an attacker-controlled shared object and execute arbitrary code with the elevated privileges of the program. Exploitation requires an installed setuid or setgid binary whose DT_RPATH uses $ORIGIN followed by ".." traversal that normalizes into a trusted directory, and the ability to hard-link that binary and win the race by swapping a path component for a symbolic link. Major Linux-based OS distributions ship with fs.protected_hardlinks enabled by default and mitigate the vulnerability.

Unauthenticated Traffic Handling Flaw Allows Packet Leakage on HPE Aruba Networking CX 10000 series switches

A vulnerability in the firewall component of HPE Aruba Networking CX 10000 Series Switches exists. It could allow an unauthenticated adjacent attacker to conduct a packet forwarding attack against the ICMP and UDP protocol. For this attack to be successful an attacker requires a switch configuration that allows packets routing (at layer 3). Configurations that do not allow network traffic routing are not impacted. Successful exploitation could allow an attacker to bypass security policies, potentially leading to unauthorized data exposure.

Windows HTTP Print Provider Remote Code Execution Vulnerability

Heap-based buffer overflow in Windows HTTP Print Provider allows an unauthorized attacker to execute code over a network.

Windows Container Manager Service Security Feature Bypass Vulnerability

Improper link resolution before file access ('link following') in Windows Container Manager Service allows an authorized attacker to bypass a security feature locally.

Heap-based buffer overflow in Windows Network File System allows an unauthorized attacker to execute code over a network.

Windows DWM Core Library Elevation of Privilege Vulnerability

Use after free in Windows DWM Core Library allows an authorized attacker to elevate privileges over a network.

There is a buffer overflow vulnerability in the underlying Utility daemon that could lead to unauthenticated remote code execution by sending specially crafted packets destined to the PAPI (Aruba's access point management protocol) UDP port (8211). Successful exploitation of this vulnerability results in the ability to execute arbitrary code as a privileged user on the underlying operating system.

Wazuh: Cluster Protocol Memory Exhaustion (DoS) via unbounded receive_str allocation and div_msg_box accumulation

Wazuh is a free and open source platform used for threat prevention, detection, and response. From 3.9.0 until 4.14.5 and 5.0.0-beta2, the Wazuh cluster protocol in framework/wazuh/core/cluster/common.py allows an authenticated cluster node to exhaust memory on the master. The receive_str() method accepts an attacker-controlled total for InBuffer without a maximum, so a new_str command can request a multi-gigabyte bytearray and repeated requests accumulate in in_str. The divided-message path also retains flag_divided fragments under unique counters in div_msg_box without a count, aggregate-size, or expiration limit. Exploitation can disrupt agent connectivity and alert processing across the monitored environment. This issue is fixed in versions 4.14.5 and 5.0.0-beta2.
