Description
This security bulletin contains information about 3 vulnerabilities.
1) Memory corruption (CVE-ID: CVE-2009-0235)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability alows a remote authenticated attacker to execute arbitrary code on the target system.
The weakness exists due to buffer overflow when parsing a malformed Word 97 document in Microsoft WordPad. A remote attacker can create a specially crafted Word file, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system with privileges of the current user.
Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.
2) Stack-based buffer overflow (CVE-ID: CVE-2009-0088)
CWE-ID: CWE-121 - Stack-based buffer overflow
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability alows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to stack overflow when parsing a malformed WordPerfect document. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system with privileges of the current user.
Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.
3) Memory corruption (CVE-ID: CVE-2009-0087)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Red
The vulnerability alows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to buffer overflow when process documents in Microsoft WordPad and Microsoft Office converter. A remote attacker can create a specially crafted Word file containing a malformed data, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system with privileges of the current user.
Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.
Note: the vulnerability was being actively exploited.
