Ichitaro 2022

An out-of-bounds write vulnerability exists in the "HyperLinkFrame" stream parser of Ichitaro 2023 1.0.1.59372. A specially crafted document can cause a type confusion, which can lead to memory corruption and eventually arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability.Show less

An integer overflow exists in the "HyperLinkFrame" stream parser of Ichitaro 2023 1.0.1.59372. A specially crafted document can cause the parser to make an under-sized allocation, which can later allow for memory corruption, potentially resulting in arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability.Show less

A use-after-free vulnerability exists in the Figure stream parsing functionality of Ichitaro 2023 1.0.1.59372. A specially crafted document can cause memory corruption, resulting in arbitrary code execution. Victim would need to open a malicious file to trigger this vulnerability.Show less

An out-of-bounds write vulnerability exists within the parsers for both the "DocumentViewStyles" and "DocumentEditStyles" streams of Ichitaro 2023 1.0.1.59372 when processing types 0x0000-0x0009 of a style record with the type 0x2008. A specially crafted document can cause memory corruption, which can lead to arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability.Show less

A heap-based buffer overflow vulnerability exists in the way Ichitaro version 2022 1.0.1.57600 processes certain LayoutBox stream record types. A specially crafted document can cause a buffer overflow, leading to memory corruption, which can result in arbitrary code execution.To trigger this vulnerability, the victim would need to open a malicious, attacker-created document.Show less

An invalid free vulnerability exists in the Frame stream parser functionality of Ichitaro 2022 1.0.1.57600. A specially crafted document can lead to an attempt to free a stack pointer, which causes memory corruption. An attacker can provide a malicious file to trigger this vulnerability.Show less

A buffer overflow vulnerability exists in the Attribute Arena functionality of Ichitaro 2022 1.0.1.57600. A specially crafted document can lead to memory corruption. An attacker can provide a malicious file to trigger this vulnerability.Show less

A use-after-free vulnerability exists within the way Ichitaro Word Processor 2022, version 1.0.1.57600, processes protected documents. A specially crafted document can trigger reuse of freed memory, which can lead to further memory corruption and potentially result in arbitrary code execution. An attacker can provide a malicious document to trigger this vulnerability.Show less
