Title
Avast antivirus use of stack memory after free when scanning a malformed PE file
Summary
Use of stack memory after free vulnerability in Avast Antivirus when scanning a malformed Windows PE file may allow Denial-of-Service of the antivirus process.
This issue affects Avast Antivirus, AVG Antivirus, Norton Antivirus, Avast One, and Avast Business Antivirus on Windows, macOS, and Linux for virus definition builds before VPS 25022500.
The affected scanning logic is delivered through a shared Gen Digital virus definition update stream. The same stream feeds the consumer antivirus products listed in this advisory and other Gen Digital products that embed the same engine. Mitigation flows through this update channel; installations at or above the listed build are not vulnerable regardless of which product consumes the stream.

Title
Malformed DATA submessage leads to bad-free error in Fast-DDS
Summary
Fast DDS is a C++ implementation of the DDS (Data Distribution Service) standard of the OMG (Object Management Group). In affected versions specific DATA submessages can be sent to a discovery locator which may trigger a free error. This can remotely crash any Fast-DDS process. The call to free() could potentially leave the pointer in the attackers control which could lead to a double free. This issue has been addressed in versions 2.12.0, 2.11.3, 2.10.3, and 2.6.7. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Title
GSS-NTLMSSP vulnerable to incorrect free when decoding target information
Summary
GSS-NTLMSSP is a mechglue plugin for the GSSAPI library that implements NTLM authentication. Prior to version 1.2.0, an incorrect free when decoding target information can trigger a denial of service. The error condition incorrectly assumes the `cb` and `sh` buffers contain a copy of the data that needs to be freed. However, that is not the case. This vulnerability can be triggered via the main `gss_accept_sec_context` entry point. This will likely trigger an assertion failure in `free`, causing a denial-of-service. This issue is fixed in version 1.2.0.

CVE-2022-31625 (GCVE-0-2022-31625)
Vulnerability from cvelistv5 – Published: 2022-06-16 05:45 – Updated: 2024-09-16 18:35

VEX
Title
Freeing unallocated memory in php_pgsql_free_params()
Summary
In PHP versions 7.4.x below 7.4.30, 8.0.x below 8.0.20, and 8.1.x below 8.1.7, when using Postgres database extension, supplying invalid parameters to the parametrized query may lead to PHP attempting to free memory using uninitialized data as pointers. This could lead to RCE vulnerability or denial of service.
Severity
8.1 (High)

Mitigation
Implementation
Only free pointers that you have called malloc on previously. This is the recommended solution. Keep track of which pointers point at the beginning of valid chunks and free them only once.
Mitigation
Implementation
Before freeing a pointer, the programmer should make sure that the pointer was previously allocated on the heap and that the memory belongs to the programmer. Freeing an unallocated pointer will cause undefined behavior in the program.
Mitigation MIT-4.6
Architecture and Design
Strategy: Libraries or Frameworks
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- For example, glibc in Linux provides protection against free of invalid pointers.
Mitigation
Architecture and Design
Use a language that provides abstractions for memory allocation and deallocation.
