Hi,
The following CVE (Common Vulnerabilities & Exposures) id was
published for pango1.0.
CVE-2009-1194[0]:
|Pango is a library for laying out and rendering text, with an emphasis
|on internationalization. Pango suffers from a multiplicative integer
|overflow which may lead to a potentially exploitable, heap overflow
|depending on the calling conditions. For example, this vulnerability is
|remotely reachable in Firefox by creating an overly large
|document.location value but only results in a process-terminating,
|allocation error (denial of service).
|
|The affected function is pango_glyph_string_set_size. An overflow check
|when doubling the size neglects the overflow possible on the subsequent
|allocation:
|
| string->glyphs = g_realloc (string->glyphs, string->space *
| sizeof (PangoGlyphInfo));
|
|Note that other font rendering subsystems suffer from similar issues and
|should be cross-checked by maintainers.
Please coordinate with the security team (t...@security.debian.org)
to prepare updates for the stable releases.
See also see USN-773-1 [1].
If you fix the vulnerability please also make sure to include the
CVE id in your changelog entry.
