Vulnerability Assessment Details

[DSA1020] DSA-1020-1 flex

Vulnerability Assessment Summary
DSA-1020-1 flex

Detailed Explanation for this Vulnerability Assessment

Chris Moore discovered that flex, a scanner generator, generates code,
which allocates insufficient memory, if the grammar contains REJECT
statements or trailing context rules. This may lead to a buffer overflow
and the execution of arbitrary code.
If you use code, which is derived from a vulnerable lex grammar in
an untrusted environment you need to regenerate your scanner with the
fixed version of flex.
The old stable distribution (woody) is not affected by this problem.
For the stable distribution (sarge) this problem has been fixed in
version 2.5.31-31sarge1.
For the unstable distribution (sid) this problem has been fixed in
version 2.5.33-1.
We recommend that you upgrade your flex package.
