Title
Segfault in `CTCBeamSearchDecoder`
Summary
TensorFlow is an end-to-end open source platform for machine learning. Due to lack of validation in `tf.raw_ops.CTCBeamSearchDecoder`, an attacker can trigger denial of service via segmentation faults. The implementation(https://github.com/tensorflow/tensorflow/blob/a74768f8e4efbda4def9f16ee7e13cf3922ac5f7/tensorflow/core/kernels/ctc_decoder_ops.cc#L68-L79) fails to detect cases when the input tensor is empty and proceeds to read data from a null buffer. The fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3 and TensorFlow 2.1.4, as these are also affected and still in supported range.

Title
Uninitialized variable bug in Exiv2
Summary
Exiv2 is a C++ library and a command-line utility to read, write, delete and modify Exif, IPTC, XMP and ICC image metadata. A read of uninitialized memory was found in Exiv2 versions v0.27.3 and earlier. Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. The read of uninitialized memory is triggered when Exiv2 is used to read the metadata of a crafted image file. An attacker could potentially exploit the vulnerability to leak a few bytes of stack memory, if they can trick the victim into running Exiv2 on a crafted image file. The bug is fixed in version v0.27.4.

CVE-2021-31417 (GCVE-0-2021-31417)
Vulnerability from cvelistv5 – Published: 2021-04-29 16:31 – Updated: 2024-08-03 22:55
VLAI
Summary
This vulnerability allows local attackers to disclose sensitive information on affected installations of Parallels Desktop 15.1.4-47270. An attacker must first obtain the ability to execute low-privileged code on the target guest system in order to exploit this vulnerability. The specific flaw exists within the Toolgate component. The issue results from the lack of proper initialization of memory prior to accessing it. An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges and execute arbitrary code in the context of the hypervisor. Was ZDI-CAN-12131.

CVE-2021-31418 (GCVE-0-2021-31418)
Vulnerability from cvelistv5 – Published: 2021-04-29 16:31 – Updated: 2024-08-03 22:55
VLAI
Summary
This vulnerability allows local attackers to disclose sensitive information on affected installations of Parallels Desktop 15.1.4-47270. An attacker must first obtain the ability to execute low-privileged code on the target guest system in order to exploit this vulnerability. The specific flaw exists within the Toolgate component. The issue results from the lack of proper initialization of memory prior to accessing it. An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges and execute arbitrary code in the context of the hypervisor. Was ZDI-CAN-12221.
Severity
6.5 (Medium)

CVE-2021-32845 (GCVE-0-2021-32845)
Vulnerability from cvelistv5 – Published: 2023-02-17 00:00 – Updated: 2025-03-10 21:09

Title
Moby HyperKit uninitialized memory use vtrnd pci_vtrnd_notify
Summary
HyperKit is a toolkit for embedding hypervisor capabilities in an application. In versions 0.20210107 and prior of HyperKit, the implementation of `qnotify` at `pci_vtrnd_notify` fails to check the return value of `vq_getchain`. This leads to `struct iovec iov;` being uninitialized and used to read memory in `len = (int) read(sc->vrsc_fd, iov.iov_base, iov.iov_len);` when an attacker is able to make `vq_getchain` fail. This issue may lead to a guest crashing the host causing a denial of service and, under certain circumstance, memory corruption. This issue is fixed in commit 41272a980197917df8e58ff90642d14dec8fe948.

CVE-2021-32846 (GCVE-0-2021-32846)
Vulnerability from cvelistv5 – Published: 2023-02-17 00:00 – Updated: 2025-03-10 21:09

Title
Moby HyperKit uninitialized memory use in virtio-sock pci_vtsock_proc_tx
Summary
HyperKit is a toolkit for embedding hypervisor capabilities in an application. In versions 0.20210107, function `pci_vtsock_proc_tx` in `virtio-sock` can lead to to uninitialized memory use. In this situation, there is a check for the return value to be less or equal to `VTSOCK_MAXSEGS`, but that check is not sufficient because the function can return `-1` if it finds an error it cannot recover from. Moreover, the negative return value will be used by `iovec_pull` in a while condition that can further lead to more corruption because the function is not designed to handle a negative `iov_len`. This issue may lead to a guest crashing the host causing a denial of service and, under certain circumstance, memory corruption. This issue is fixed in commit af5eba2360a7351c08dfd9767d9be863a50ebaba.

CVE-2021-34855 (GCVE-0-2021-34855)
Vulnerability from cvelistv5 – Published: 2021-10-25 17:10 – Updated: 2024-08-04 00:26
VLAI
Summary
This vulnerability allows local attackers to disclose sensitive information on affected installations of Parallels Desktop 16.1.3 (49160). An attacker must first obtain the ability to execute low-privileged code on the target guest system in order to exploit this vulnerability. The specific flaw exists within the Toolgate component. The issue results from the lack of proper initialization of memory prior to accessing it. An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges and execute arbitrary code in the context of the hypervisor. Was ZDI-CAN-13592.

Mitigation
Phase: Implementation
Description:
- Explicitly initialize the resource before use. If this is performed through an API function or standard procedure, follow all required steps.
Mitigation
Phase: Implementation
Description:
- Pay close attention to complex conditionals that affect initialization, since some branches might not perform the initialization.
Mitigation
Phase: Implementation
Description:
- Avoid race conditions (CWE-362) during initialization routines.
Mitigation
Phase: Build and Compilation
Description:
- Run or compile the product with settings that generate warnings about uninitialized variables or data.
No CAPEC attack patterns related to this CWE.
