Directory traversal vulnerability in install.php in Piwigo before 2.4.7 allows remote attackers to read and delete arbitrary files via a .. (dot dot) in the dl parameter.

Heap-based buffer overflow in the pango_ft2_font_render_box_glyph function in pango/pangoft2-render.c in libpango in Pango 1.28.3 and earlier, when the FreeType2 backend is enabled, allows user-assisted remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted font file, related to the glyph box for an FT_Bitmap object.

Multiple cross-site scripting (XSS) vulnerabilities in register.php in Piwigo 2.0.9 and earlier allow remote attackers to inject arbitrary web script or HTML via the (1) login and (2) mail_address parameters.

Integer overflow in the pango_glyph_string_set_size function in pango/glyphstring.c in Pango before 1.24 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a long glyph string that triggers a heap-based buffer overflow, as demonstrated by a long document.location value in Firefox.
