CVE-2021-33105: INTEL-SA-00481

Solution Manager (Diagnostics Root Cause Analysis Tools) - version 720, allows an administrator to execute code on all connected Diagnostics Agents and browse files on their systems. An attacker could thereby control the managed systems. It is considered that this is a missing segregation of duty for the SAP Solution Manager administrator. Impacts of unauthorized execution of commands can lead to sensitive information disclosure, loss of system integrity and denial of service.

CVE-2022-22544

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:

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.

             : utility, included in the zip package, creates zip archives.  Zip and
             : unzip are both compatible with archives created by PKWARE(R)'s PKZIP
             : for MS-DOS, but the programs' options and default behaviors do differ
             : in some respects.
             : 
             : Install the unzip package if you need to list, test or extract files from
             : a zip archive.
