Description
This security bulletin contains information about 3 secuirty vulnerabilities.
1) Integer overflow (CVE-ID: CVE-2020-10531)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in UnicodeString::doAppend() function in common/unistr.cpp. A remote attacker can pass specially crafted string to the application that is using the vulnerable library, trigger integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Stack-based buffer overflow (CVE-ID: CVE-2011-4599)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the _canonicalize function in common/uloc.c when processing a crafted locale ID that is not properly handled during variant canonicalization. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Heap-based buffer overflow (CVE-ID: CVE-2014-8146)
The vulnerability allows a remote attacker to cause Dos condition or execute arbitrary code on the target system.
The vulnerability exists due to heap-based buffer overflow when the resolveImplicitLevels function in common/ubidi.c in the Unicode Bidirectional Algorithm implementation in ICU4C does not properly track directionally isolated pieces of text. A remote unauthenticated attacker can supply specially crafted text file, trigger memory corruption and cause the service to crash or execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
