*INTRODUCTION*
Passkeys on Android are stored in Google Password Manager by default. The user cannot make their own backups of them.

not contain any secrets, rendering them useless.

Also note that Google Passkey Manager appears to primarily be a CLOUD-based password manager (with copies of passwords

NULL pointer dereference in the function handle_viminfo_register() of vim

Meng,

https://github.com/vim/vim/commit/0a0764684591c7c6a5d722b628f11dc96208e853

I have no idea, why this issue is worth a CVE, because if an attacker
can modify your .viminfo file to make Vim crash, he already has the
possibilities to do much more harm directly. So I don't think this is
particular useful CVE. I'd also like to dispute this.

Thanks,

Re: Buffer Overflow in graphviz via via a crafted config6a file

More specifically, this issue is an out-of-bounds read.

AFAICT the issue was actually introduced in Graphviz 2.36. It was fixed
in commit a95f977f5d809915ec4b14836d2b5b7f5e74881e (essentially
reverting cf95714837f06f684929b54659523c2c9b1fc19f that introduced the
issue), but there has been no release yet since then. The next release
will be 10.0.0. So affected versions would be [2.36, 10.0.0).

In regards to your recent FD posts, are you requesting CVEs based on the
presence of strings in commit messages such as "null pointer dereference"?

Are you reaching out to each upstream project before assigning a CVE? Do
you believe that every null pointer bug is a vulnerability? What impact
are you hoping to achieve?

Please reconsider how you are requesting CVEs.

I will be asking that this CVE be withdrawn on behalf of the X.Org security team.

While it is a low-priority bug, we did not see any security exposure
when this bug was first brought to our attention because there is no
way for an attacker to change the contents of the lisp.lsp file or to
cause a *.lsp file to be loaded for another user.

Misues same epoch number within TCP lifetime in TinyDTLS

Posted by Meng Ruijie on Jan 17

[Suggested description]
An issue was discovered in Contiki-NG tinyDTLS through 2018-08-30. DTLS servers allow remote attackers to reuse the
same epoch number within two times the TCP maximum segment lifetime, which is prohibited in RFC6347. This vulnerability
allows remote attackers to obtain sensitive application (data of connected clients).

Buffer over-read in dtls_sha256_update of TinyDTLS

Posted by Meng Ruijie on Jan 17

[Suggested description]
An issue was discovered in Contiki-NG tinyDTLS through 2018-08-30. A buffer over-read exists in the dtls_sha256_update
function. This bug allows remote attackers to cause a denial of service (crash) and possibly read sensitive information
by sending a malformed packet with an over-large fragment length field, due to servers incorrectly handling malformed
packets.

Legends of IdleOn - I Reject Your RNG And Substitute My Own

Posted by Soatok Dreamseeker on Jan 17

Hello Full Disclosure mailing list!

Legends of IdleOn is a popular free-to-play game on Android, iOS, Steam,
and Web. While playing around with it last year, I got curious and noticed
a trivial way to manipulate the random number generator.

After six months of radio silence from the developer, including asking the
Discord moderators for help getting the developer's attention, I've decided
to publish this publicly:...

Re: cpio privilege escalation vulnerability via setuid files in cpio archive

Posted by Harry Sintonen via Fulldisclosure on Jan 14

Tar does set setuid bit, but tar is not vulnerable. This is not an attack.

The user is responsible for extracting the archives to secure location
and not letting other users access to insecure setuid binaries. See:

https://www.gnu.org/software/tar/manual/html_section/Security.html#Security-rules-of-thumb

These same security considerations also apply to cpio.

Re: cpio privilege escalation vulnerability via setuid files in cpio archive

Posted by Harry Sintonen via Fulldisclosure on Jan 14

So does for example tar. The same rules that apply to tar also apply to
cpio:

"Extract from an untrusted archive only into an otherwise-empty directory.
This directory and its parent should be accessible only to trusted users."

This is a user error, not a vulnerability in cpio.
