GHSA-JW75-VVJ8-5H3F

Vulnerability from github – Published: 2022-05-24 17:41 – Updated: 2023-05-24 15:30
VLAI
Details

In OpenWrt 19.07.x before 19.07.7, when IPv6 is used, a routing loop can occur that generates excessive network traffic between an affected device and its upstream ISP's router. This occurs when a link prefix route points to a point-to-point link, a destination IPv6 address belongs to the prefix and is not a local IPv6 address, and a router advertisement is received with at least one global unique IPv6 prefix for which the on-link flag is set. This affects the netifd and odhcp6c packages.

GHSA-JXPF-XQ2M-Q525

Vulnerability from github – Published: 2026-04-22 22:09 – Updated: 2026-05-13 13:33
VLAI
Summary
OpenMcdf has an Infinite loop DoS via crafted CFB directory cycle
Details

Summary

OpenMcdf does not detect cycles in the directory entry red-black tree of a Compound File Binary (CFB) document. A crafted CFB file with a cycle in the LeftSiblingID / RightSiblingID chain causes Storage.EnumerateEntries() and Storage.OpenStream() to loop indefinitely, consuming the calling thread with no possibility of recovery via try/catch.

Details

CFB directory entries form a red-black tree linked by LeftSiblingID and RightSiblingID fields. OpenMcdf's DirectoryTreeEnumerator and DirectoryTree.TryGetDirectoryEntry traverse this tree without tracking visited node IDs, so a crafted cycle (e.g. entry A's RightSiblingID points to entry B, and entry B's LeftSiblingID points back to entry A) causes traversal to loop indefinitely.

Two distinct code paths are affected:

  • Storage.EnumerateEntries() - DirectoryTreeEnumerator.MoveNext() never returns false; the same entry is yielded on every iteration and the caller's foreach never exits. Heap grows unboundedly as entries accumulate.
  • Storage.OpenStream() - DirectoryTree.TryGetDirectoryEntry loops indefinitely inside DirectoryEntries.TryGetSibling during the name lookup.

PoC

A crafted CFB file with a sibling cycle (see attached) triggers the issue with the following code:

using OpenMcdf;

using var ms = new MemoryStream(File.ReadAllBytes("crafted.cfb"));
using var root = RootStorage.Open(ms);

// Never returns - EnumerateEntries loops indefinitely
foreach (var entry in root.EnumerateEntries())
{
    Console.WriteLine(entry.Name);

    if (entry.Type == EntryType.Stream)
        root.OpenStream(entry.Name); // also hangs depending on the cycle structure
}

Impact

A denial of service affecting any application that opens untrusted CFB files with OpenMcdf. A small crafted input carrying a valid CFB magic header (D0 CF 11 E0 A1 B1 1A E1) is sufficient to pass initial format validation and reach the vulnerable traversal code. No exception is thrown, so try/catch cannot protect callers. The affected thread is unrecoverable without killing the process.

GHSA-JXV8-JMP2-87P8

Vulnerability from github – Published: 2024-08-07 18:30 – Updated: 2025-11-04 00:31
VLAI
Details

In the Linux kernel, the following vulnerability has been resolved:

x86/bhi: Avoid warning in #DB handler due to BHI mitigation

When BHI mitigation is enabled, if SYSENTER is invoked with the TF flag set then entry_SYSENTER_compat() uses CLEAR_BRANCH_HISTORY and calls the clear_bhb_loop() before the TF flag is cleared. This causes the #DB handler (exc_debug_kernel()) to issue a warning because single-step is used outside the entry_SYSENTER_compat() function.

To address this issue, entry_SYSENTER_compat() should use CLEAR_BRANCH_HISTORY after making sure the TF flag is cleared.

The problem can be reproduced with the following sequence:

$ cat sysenter_step.c int main() { asm("pushf; pop %ax; bts $8,%ax; push %ax; popf; sysenter"); }

$ gcc -o sysenter_step sysenter_step.c

$ ./sysenter_step Segmentation fault (core dumped)

The program is expected to crash, and the #DB handler will issue a warning.

This causes the #DB handler\n(exc_debug_kernel()) to issue a warning because single-step is used outside the\nentry_SYSENTER_compat() function.\n\nTo address this issue, entry_SYSENTER_compat() should use CLEAR_BRANCH_HISTORY\nafter making sure the TF flag is cleared.\n\nThe problem can be reproduced with the following sequence:\n\n  $ cat sysenter_step.c\n  int main()\n  { asm(\"pushf; pop %ax; bts $8,%ax; push %ax; popf; sysenter\"); }\n\n  $ gcc -o sysenter_step sysenter_step.c\n\n  $ ./sysenter_step\n  Segmentation fault (core dumped)\n\nThe program is expected to crash, and the #DB handler will issue a warning.\n\nKernel log:\n\n  WARNING: CPU: 27 PID: 7000 at arch/x86/kernel/traps.c:1009 exc_debug_kernel+0xd2/0x160\n  ...\n  RIP: 0010:exc_debug_kernel+0xd2/0x160\n  ...\n  Call Trace:\n  \u003c#DB\u003e\n   ? show_regs+0x68/0x80\n   ? __warn+0x8c/0x140\n   ? exc_debug_kernel+0xd2/0x160\n   ? report_bug+0x175/0x1a0\n   ? handle_bug+0x44/0x90\n   ? exc_invalid_op+0x1c/0x70\n   ? asm_exc_invalid_op+0x1f/0x30\n   ? exc_debug_kernel+0xd2/0x160\n   exc_debug+0x43/0x50\n   asm_exc_debug+0x1e/0x40\n  RIP: 0010:clear_bhb_loop+0x0/0xb0\n  ...\n  \u003c/#DB\u003e\n  \u003cTASK\u003e\n   ? entry_SYSENTER_compat_after_hwframe+0x6e/0x8d\n  \u003c/TASK\u003e\n\n  [ bp: Massage commit message. ]",

Summary
pypdf: Possible infinite loop when processing outlines/bookmarks in writer
Details

Impact

An attacker who uses this vulnerability can craft a PDF which leads to an infinite loop. This requires merging a file with outlines into a writer.

Patches

This has been fixed in pypdf==6.13.0.

Workarounds

If you cannot upgrade yet, consider applying the changes from PR #3830.
