Name of the Vulnerable Software and Affected Versions
International Components for Unicode (ICU) for C/C++ versions through 66.1
Description
An issue exists in the UnicodeString::doAppend() function in common/unistr.cpp, related to an integer overflow that leads to a heap-based buffer overflow. This could allow a remote attacker to gain unauthorized access to confidential data, cause a denial of service, or impact data integrity.
Recommendations
For versions through 66.1, consider disabling the
UnicodeString::doAppend() function as a temporary workaround until a patch is available. Restrict access to the common/unistr.cpp module to minimize the risk of exploitation.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.DoS
