Heap-based Buffer Overflow

A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().

Vim is an open source, command line text editor. Prior to version 9.1.2132, a heap buffer overflow vulnerability exists in Vim's tag file resolution logic when processing the 'helpfile' option. The vulnerability is located in the get_tagfname() function in src/tag.c. When processing help file tags, Vim copies the user-controlled 'helpfile' option value into a fixed-size heap buffer of MAXPATHL + 1 bytes (typically 4097 bytes) using an unsafe STRCPY() operation without any bounds checking. This issue has been patched in version 9.1.2132.Show less

Fast DDS is a C++ implementation of the DDS (Data Distribution Service) standard of the OMG (Object Management Group ). Prior to versions 3.4.1, 3.3.1, and 2.6.11, a heap buffer overflow exists in the Fast-DDS DATA_FRAG receive path. An un authenticated sender can transmit a single malformed RTPS DATA_FRAG packet where `fragmentSize` and `sampleSize` are craft ed to violate internal assumptions. Due to a 4-byte alignment step during fragment metadata initialization, the code write s past the end of the allocated payload buffer, causing immediate crash (DoS) and potentially enabling memory corruption ( RCE risk). Versions 3.4.1, 3.3.1, and 2.6.11 patch the issue.Show less

Fast DDS is a C++ implementation of the DDS (Data Distribution Service) standard of the OMG (Object Management Group ). Prior to versions 3.4.1, 3.3.1, and 2.6.11, when the security mode is enabled, modifying the DATA Submessage within an SPDP packet sent by a publisher causes a heap buffer overflow, resulting in remote termination of Fast-DDS. If the fields of `PID_IDENTITY_TOKEN` or `PID_PERMISSIONS_TOKEN` in the DATA Submessage are tampered with — specially `readOctetVector` reads an unchecked `vecsize` that is propagated unchanged into `readData` as the `length` parameter — the attacker-contro lled `vecsize` can trigger a 32-bit integer overflow during the `length` calculation. That overflow can cause large alloca tion attempt that quickly leads to OOM, enabling a remotely-triggerable denial-of-service and remote process termination. Versions 3.4.1, 3.3.1, and 2.6.11 patch the issue.Show less

Prior to versions 3.4.1, 3.3.1, and 2.6.11, when the security mode is enabled, modifying the DATA Submessage within an SPDP packet sent by a publisher causes a heap buffer overflow, resulting in remote termination of Fast-DDS. If the fields of `PID_IDENTITY_TOKEN` or `PID_PERMISSIONS_TOKEN` in the DATA Submessage — specifically by tampering with the `str_size` value read by `readString` (called from `readBinaryProperty`) — are modified, a 32-bit integer overflow can occur, causing `std::vector::resize` to use an attacker-controlled size and quickly trigger heap buffer overflow and remote process term ination. Versions 3.4.1, 3.3.1, and 2.6.11 patch the issue.Show less
