Debian: DSA-1854-1 Alert: Potential APR Heap Overflow Vulnerability

Matt Lewis discovered that the memory management code in the Apache
Portable Runtime (APR) library does not guard against a wrap-around
during size computations. This could cause the library to return a
memory area which smaller than requested, resulting a heap overflow
and possibly arbitrary code execution.

For the old stable distribution (etch), this problem has been fixed in
version 1.2.7-9 of the apr package, and version 1.2.7+dfsg-2+etch3 of
the apr-util package.

For the stable distribution (lenny), this problem has been fixed in
version 1.2.12-5+lenny1 of the apr package and version 1.2.12-5+lenny1
of the apr-util package.

For the unstable distribution (sid), this problem will be fixed soon.

We recommend that you upgrade your APR packages.
