Libxml2: unbounded relaxng include recursion leading to stack overflow

A flaw was identified in the RelaxNG parser of libxml2 related to how external schema inclusions are handled. The parser does not enforce a limit on inclusion depth when resolving nested <include> directives. Specially crafted or overly complex schemas can cause excessive recursion during parsing. This may lead to stack exhaustion and application crashes, creating a denial-of-service risk.

Libnbd: libnbd: arbitrary code execution via ssh argument injection through a malicious uri

A flaw was found in libnbd. A malicious actor could exploit this by convincing libnbd to open a specially crafted Uniform Resource Identifier (URI). This vulnerability arises because non-standard hostnames starting with '-o' are incorrectly interpreted as arguments to the Secure Shell (SSH) process, rather than as hostnames. This could lead to arbitrary code execution with the privileges of the user running libnbd.

wolfSSL Python library `CERT_REQUIRED` mode fails to enforce client certificate requirement

A vulnerability in the handling of verify_mode = CERT_REQUIRED in the wolfssl Python package (wolfssl-py) causes client certificate requirements to not be fully enforced.  Because the WOLFSSL_VERIFY_FAIL_IF_NO_PEER_CERT flag was not included, the behavior effectively matched CERT_OPTIONAL: a peer certificate was verified if presented, but connections were incorrectly authenticated when no client certificate was provided.  This results in improper authentication, allowing attackers to bypass mutual TLS (mTLS) client authentication by omitting a client certificate during the TLS handshake.  The issue affects versions up to and including 5.8.2.

Wget2: gnu wget2: memory corruption and crash via filename sanitization logic with attacker-controlled urls

A flaw was found in GNU Wget2. This vulnerability, a stack-based buffer overflow, occurs in the filename sanitization logic when processing attacker-controlled URL paths, particularly when filename restriction options are active. A remote attacker can exploit this by providing a specially crafted URL, which, upon user interaction with wget2, can lead to memory corruption. This can cause the application to crash and potentially allow for further malicious activities.

Limited HTML injection in emails

Emails sent by pretix can utilize placeholders that will be filled with customer data. For example, when {name} is used in an email template, it will be replaced with the buyer's name for the final email. If the name of the attendee contained HTML or Markdown formatting, this was rendered as HTML in the resulting email. This way, a user could inject links or other formatted text through a maliciously formatted name. Since pretix applies a strict allow list approach to allowed HTML tags, this could not be abused for XSS or similarly dangerous attack chains. However, it can be used to manipulate emails in a way that makes user-provided content appear in a trustworthy and credible way, which can be abused for phishing.

Genymobile/scrcpy <= 3.3.3 Global Buffer Overflow

Genymobile/scrcpy versions up to and including 3.3.3 and prior to commit 3e40b24 contain a global buffer overflow vulnerability in the function sc_read32be, invoked via sc_device_msg_deserialize() and process_msgs(). Processing crafted device messages can cause reads beyond the bounds of a global buffer, leading to memory corruption or crashes. This vulnerability can be exploited to cause a denial of service and, under certain conditions, may be leveraged for further exploitation depending on the execution environment and available mitigations.

wb2osz/direwolf <= 1.8 Stack-based Buffer Overflow DoS

wb2osz/direwolf (Dire Wolf) versions up to and including 1.8, prior to commit 694c954, contain a stack-based buffer overflow vulnerability in the function kiss_rec_byte() located in src/kiss_frame.c. When processing crafted KISS frames that reach the maximum allowed frame length (MAX_KISS_LEN), the function appends a terminating FEND byte without reserving sufficient space in the stack buffer. This results in an out-of-bounds write followed by an out-of-bounds read during the subsequent call to kiss_unwrap(), leading to stack memory corruption or application crashes. This vulnerability may allow remote unauthenticated attackers to trigger a denial-of-service condition.
