GHSA-HH8H-HXCJ-2PM7

Vulnerability from github – Published: 2026-05-17 21:30 – Updated: 2026-05-18 15:30

Details

Crypt::OpenSSL::PKCS12 versions through 1.94 for Perl truncates passwords with embedded NULLs.

Password parameters in PKCS12.xs are declared char *, which routes through Perl's default typemap to SvPV_nolen. The Perl length is discarded.

The C code (or OpenSSL internally) calls strlen() on the buffer. Any password byte at or after the first NULL is silently dropped. Binary / KDF-derived / HMAC-derived passwords lose entropy without any warnings.

Severity

9.8 (Critical)

GHSA-P34H-WQ7J-H5V6

Vulnerability from github – Published: 2025-10-10 22:53 – Updated: 2025-10-13 15:47

Summary

python-ldap is Vulnerable to Improper Encoding or Escaping of Output and Improper Null Termination

Details

Summary

ldap.dn.escape_dn_chars() escapes \x00 incorrectly by emitting a backslash followed by a literal NUL byte instead of the RFC-4514 hex form \00. Any application that uses this helper to construct DNs from untrusted input can be made to consistently fail before a request is sent to the LDAP server (e.g., AD), resulting in a client-side denial of service.

Details

Affected function: ldap.dn.escape_dn_chars(s)

File: Lib/ldap/dn.py

Buggy behavior: For NUL, the function does:

s = s.replace('\000', '\\\000') # backslash + literal NUL

This produces Python strings which, when passed to python-ldap APIs (e.g., add_s, modify_s, rename_s, or used as search bases), contain an embedded NUL. python-ldap then raises ValueError: embedded null character (or otherwise fails) before any network I/O. With correct RFC-4514 encoding (\00), the client proceeds and the server can apply its own syntax rules (e.g., AD will reject NUL in CN with result: 34), proving the failure originates in the escaping helper.

Why it matters: Projects follow the docs which state this function “should be used when building LDAP DN strings from arbitrary input.” The function’s guarantee is therefore relied upon as a safety API. A single NUL in attacker-controlled input reliably breaks client workflows (crash/unhandled exception, stuck retries, poison queue record), i.e., a DoS.

Standards: RFC 4514 requires special characters and controls to be escaped using hex form; a literal NUL is not a valid DN character.

Minimal fix: Escape NUL as hex:

s = s.replace('\x00', r'\00')

PoC

Prereqs: Any python-ldap install and a reachable LDAP server (for the second half). The first half (client-side failure) does not require a live server.

```import ldap from ldap.dn import escape_dn_chars, str2dn

l = ldap.initialize("ldap://10.0.1.11") # your lab DC/LDAP l.protocol_version = 3 l.set_option(ldap.OPT_REFERRALS, 0) l.simple_bind_s(r"DSEC\dani.aga", "PassAa1")

--- Attacker-controlled value contains NUL ---

cn = "bad\0name" escaped_cn = escape_dn_chars(cn) dn = f"CN={escaped_cn},OU=Users,DC=dsec,DC=local" attrs = [('objectClass', [b'user']), ('sAMAccountName', [b'badsam'])]

print("=== BUGGY DN (contains literal NUL) ===") print("escaped_cn repr:", repr(escaped_cn)) print("dn repr:", repr(dn)) print("contains NUL?:", "\x00" in dn, "at index:", dn.find("\x00"))

print("=> add_s(buggy DN): expected client-side failure (no server contact)") try: l.add_s(dn, attrs) print("add_s(buggy): succeeded (unexpected)") except Exception as e: print("add_s(buggy):", type(e).name, e) # ValueError: embedded null character

--- Correct hex escape demonstrates the client proceeds to the server ---

safe_dn = dn.replace("\x00", r"\00") # RFC 4514-compliant print("\n=== HEX-ESCAPED DN (\00) ===") print("safe_dn repr:", repr(safe_dn)) print("=> sanity parse:", str2dn(safe_dn)) # parses locally

print("=> add_s(safe DN): reaches server (AD will likely reject with 34)") try: l.add_s(safe_dn, attrs) print("add_s(safe): success (unlikely without required attrs/rights)") except ldap.LDAPError as e: print("add_s(safe):", e.class.name, e) # e.g., result 34 Invalid DN syntax (AD forbids NUL in CN) ```

Observed result (example):

add_s(buggy): ValueError embedded null character ← client-side DoS

add_s(safe): INVALID_DN_SYNTAX (result 34, BAD_NAME) ← request reached server; rejection due to server policy, not client bug

Impact

Type: Denial of Service (client-side).

Who is impacted: Any application that uses ldap.dn.escape_dn_chars() to build DNs from (partially) untrusted input—e.g., user creation/rename tools, sync/ETL jobs, portals allowing self-service attributes, device onboarding, batch imports. A single crafted value with \x00 reliably forces exceptions/failures and can crash handlers or jam pipelines with poison records.

Severity

5.5 (Medium)

  "details": "### Summary\n\n\n`ldap.dn.escape_dn_chars()` escapes `\\x00` incorrectly by emitting a backslash followed by a literal NUL byte instead of the RFC-4514 hex form `\\00`. Any application that uses this helper to construct DNs from untrusted input can be made to consistently fail before a request is sent to the LDAP server (e.g., AD), resulting in a client-side denial of service.\n\n\n\n### Details\n\n\n\nAffected function: `ldap.dn.escape_dn_chars(s)`\n\nFile: Lib/ldap/dn.py\n\nBuggy behavior:\nFor NUL, the function does:\n\n`s = s.replace(\u0027\\000\u0027, \u0027\\\\\\000\u0027)  # backslash + literal NUL`\n\nThis produces Python strings which, when passed to python-ldap APIs (e.g., `add_s`, `modify_s`, r`ename_s`, or used as search bases), contain an embedded NUL. python-ldap then raises ValueError: embedded null character (or otherwise fails) before any network I/O.\nWith correct RFC-4514 encoding (`\\00`), the client proceeds and the server can apply its own syntax rules (e.g., AD will reject NUL in CN with result: 34), proving the failure originates in the escaping helper.\n\nWhy it matters: Projects follow the docs which state this function \u201cshould be used when building LDAP DN strings from arbitrary input.\u201d The function\u2019s guarantee is therefore relied upon as a safety API. A single NUL in attacker-controlled input reliably breaks client workflows (crash/unhandled exception, stuck retries, poison queue record), i.e., a DoS.\n\nStandards: RFC 4514 requires special characters and controls to be escaped using hex form; a literal NUL is not a valid DN character.\n\nMinimal fix: Escape NUL as hex:\n\n`s = s.replace(\u0027\\x00\u0027, r\u0027\\00\u0027)`\n\n\n\n### PoC\n\nPrereqs: Any python-ldap install and a reachable LDAP server (for the second half). The first half (client-side failure) does not require a live server.\n\n```import ldap\nfrom ldap.dn import escape_dn_chars, str2dn\n\nl = ldap.initialize(\"ldap://10.0.1.11\")              # your lab DC/LDAP\nl.protocol_version = 3\nl.set_option(ldap.OPT_REFERRALS, 0)\nl.simple_bind_s(r\"DSEC\\dani.aga\", \"PassAa1\")         \n\n# --- Attacker-controlled value contains NUL ---\ncn = \"bad\\0name\"\nescaped_cn = escape_dn_chars(cn)\ndn = f\"CN={escaped_cn},OU=Users,DC=dsec,DC=local\"\nattrs = [(\u0027objectClass\u0027, [b\u0027user\u0027]), (\u0027sAMAccountName\u0027, [b\u0027badsam\u0027])]\n\nprint(\"=== BUGGY DN (contains literal NUL) ===\")\nprint(\"escaped_cn repr:\", repr(escaped_cn))\nprint(\"dn repr:\", repr(dn))\nprint(\"contains NUL?:\", \"\\x00\" in dn, \"at index:\", dn.find(\"\\x00\"))\n\nprint(\"=\u003e add_s(buggy DN): expected client-side failure (no server contact)\")\ntry:\n    l.add_s(dn, attrs)\n    print(\"add_s(buggy): succeeded (unexpected)\")\nexcept Exception as e:\n    print(\"add_s(buggy):\", type(e).__name__, e)  # ValueError: embedded null character\n\n# --- Correct hex escape demonstrates the client proceeds to the server ---\nsafe_dn = dn.replace(\"\\x00\", r\"\\00\")                 # RFC 4514-compliant\nprint(\"\\n=== HEX-ESCAPED DN (\\\\00) ===\")\nprint(\"safe_dn repr:\", repr(safe_dn))\nprint(\"=\u003e sanity parse:\", str2dn(safe_dn))           # parses locally\n\nprint(\"=\u003e add_s(safe DN): reaches server (AD will likely reject with 34)\")\ntry:\n    l.add_s(safe_dn, attrs)\n    print(\"add_s(safe): success (unlikely without required attrs/rights)\")\nexcept ldap.LDAPError as e:\n    print(\"add_s(safe):\", e.__class__.__name__, e)  # e.g., result 34 Invalid DN syntax (AD forbids NUL in CN)\n```\n\nObserved result (example):\n\n`add_s(buggy): ValueError embedded null character` \u2190 client-side DoS\n\n`add_s(safe): INVALID_DN_SYNTAX (result 34, BAD_NAME)` \u2190 request reached server; rejection due to server policy, not client bug\n\n\n### Impact\n\nType: Denial of Service (client-side).\n\nWho is impacted: Any application that uses ldap.dn.escape_dn_chars() to build DNs from (partially) untrusted input\u2014e.g., user `creation/rename tools`, `sync/ETL jobs`, portals allowing self-service attributes, device onboarding, batch imports.

GHSA-PJV8-58QR-6MXX

Vulnerability from github – Published: 2026-03-26 21:31 – Updated: 2026-03-27 00:31

Details

A flaw was found in GIMP. Heap-buffer-overflow vulnerability exists in the fread_pascal_string function when processing a specially crafted PSD (Photoshop Document) file. This occurs because the buffer allocated for a Pascal string is not properly null-terminated, leading to an out-of-bounds read when strlen() is subsequently called. Successfully exploiting this vulnerability can cause the application to crash, resulting in an application level Denial of Service.

Severity

2.8 (Low)
