Description:
Qiao Zhang has reported a vulnerability in vb2c, allowing malicious people to compromise a vulnerable system.
The vulnerability is caused due to a boundary error in the "parse()" function, which is used when converting vb files into c. This can be exploited to cause a buffer overflow via specially crafted vb code.
Successful exploitation allows execution of arbitrary code, but requires that a user is tricked into converting a malicious vb file.
The vulnerability has been reported in version 0.02. Prior versions may also be affected.
Solution:
Do not open vb files from untrusted sources.
Use another product.
