Description:
Limin Wang has reported a vulnerability in abcm2ps, allowing malicious people to compromise a vulnerable system.

The vulnerability is caused due to a boundary error in the "put_words()" function, which is used when converting abc files into ps format. This can be exploited to cause a buffer overflow via a specially crafted abc document.

Successful exploitation allows execution of arbitrary code, but requires that a user is tricked into converting a malicious abc document.

The vulnerability has been reported in 3.7.20. Prior versions may also be affected.

Solution:
Do not open abc files from untrusted sources.

Use another product.

Changelog:
2004-12-22: Added CVE reference.
