Security Vulnerabilities

gnark is a fast zk-SNARK library that offers a high-level API to design circuits. Versions prior to 0.11.0 have a soundness issue - in case of multiple commitments used inside the circuit the prover is able to choose all but the last commitment. As gnark uses the commitments for optimized non-native multiplication, lookup checks etc. as random challenges, then it could impact the soundness of the whole circuit. However, using multiple commitments has been discouraged due to the additional cost to the verifier and it has not been supported in the recursive in-circuit Groth16 verifier and Solidity verifier. gnark's maintainers expect the impact of the issue be very small - only for the users who have implemented the native Groth16 verifier or are using it with multiple commitments. We do not have information of such users. The issue has been patched in version 0.11.0. As a workaround, users should follow gnark maintainers' recommendation to use only a single commitment and then derive in-circuit commitments as needed using the `std/multicommit` package.
gnark is a fast zk-SNARK library that offers a high-level API to design circuits. Prior to version 0.11.0, commitments to private witnesses in Groth16 as implemented break the zero-knowledge property. The vulnerability affects only Groth16 proofs with commitments. Notably, PLONK proofs are not affected. The vulnerability affects the zero-knowledge property of the proofs - in case the witness (secret or internal) values are small, then the attacker may be able to enumerate all possible choices to deduce the actual value. If the possible choices for the variables to be committed is large or there are many values committed, then it would be computationally infeasible to enumerate all valid choices. It doesn't affect the completeness/soundness of the proofs. The vulnerability has been fixed in version 0.11.0. The patch to fix the issue is to add additional randomized value to the list of committed value at proving time to mask the rest of the values which were committed. As a workaround, the user can manually commit to a randomized value.

In the Linux kernel, the following vulnerability has been resolved:
media: aspeed: Fix memory overwrite if timing is 1600x900
When capturing 1600x900, system could crash when system memory usage is
tight.
The way to reproduce this issue:
1. Use 1600x900 to display on host
2. Mount ISO through 'Virtual media' on OpenBMC's web
3. Run script as below on host to do sha continuously
#!/bin/bash
while [ [1] ];
do
find /media -type f -printf '"%h/%f"\n' | xargs sha256sum
done
4. Open KVM on OpenBMC's web
The size of macro block captured is 8x8. Therefore, we should make sure
the height of src-buf is 8 aligned to fix this issue.
In the Linux kernel, the following vulnerability has been resolved:
media: dvb-usb-v2: af9035: Fix null-ptr-deref in af9035_i2c_master_xfer
In af9035_i2c_master_xfer, msg is controlled by user. When msg[i].buf
is null and msg[i].len is zero, former checks on msg[i].buf would be
passed. Malicious data finally reach af9035_i2c_master_xfer. If accessing
msg[i].buf[0] without sanity check, null ptr deref would happen.
We add check on msg[i].len to prevent crash.

The WP-Recall – Registration, Profile, Commerce & More plugin for WordPress is vulnerable to privilege escalation/account takeover in all versions up to, and including, 16.26.8. This is due to to plugin not properly verifying a user's identity during new order creation. This makes it possible for unauthenticated attackers to supply any email through the user_email field and update the password for that user during new order creation. This requires the commerce addon to be enabled in order to exploit.
The WP AdCenter – Ad Manager & Adsense Ads plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘ad_alignment’ attribute in all versions up to, and including, 2.5.6 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
The Frontend Post Submission Manager Lite – Frontend Posting WordPress Plugin plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the save_global_settings and process_form_edit functions in all versions up to, and including, 1.2.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update the plugin's settings and forms.
The LifterLMS – WP LMS for eLearning, Online Courses, & Quizzes plugin for WordPress is vulnerable to blind SQL Injection via the 'order' parameter in all versions up to, and including, 7.7.5 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
The WP ULike WordPress plugin before 4.7.2.1 does not properly sanitize user display names when rendering on a public page.
