Gnome : Security Vulnerabilities, CVEs, (Overflow)

Buffer overflow in GNOME libraries 1.0.8 allows local user to gain root access via a long --espeaker argument in programs such as nethack.

Buffer overflow in the XDMCP parsing code of GNOME gdm, KDE kdm, and wdm allows remote attackers to execute arbitrary commands or cause a denial of service via a long FORWARD_QUERY request.

Buffer overflow in the permitted function of GNOME gtop daemon (libgtop_daemon) in libgtop 1.0.13 and earlier may allow remote attackers to execute arbitrary code via long authentication data.

Buffer overflow in efstools in Bonobo, when installed setuid, allows local users to execute arbitrary code via long command line arguments.

Buffer overflow in gbnserver for Gnome Batalla Naval 1.0.4 allows remote attackers to execute arbitrary code via a long connection string.

Integer overflow in pixbuf_create_from_xpm (io-xpm.c) in the XPM image decoder for gtk+ 2.4.4 (gtk2) and earlier, and gdk-pixbuf before 0.22, allows remote attackers to execute arbitrary code via certain n_col and cpp values that enable a heap-based buffer overflow. NOTE: this identifier is ONLY for gtk+. It was incorrectly referenced in an advisory for a different issue (CVE-2004-0687).

Stack-based buffer overflow in xpm_extract_color (io-xpm.c) in the XPM image decoder for gtk+ 2.4.4 (gtk2) and earlier, and gdk-pixbuf before 0.22, may allow remote attackers to execute arbitrary code via a certain color string. NOTE: this identifier is ONLY for gtk+. It was incorrectly referenced in an advisory for a different issue (CVE-2004-0688).

Integer overflow in the ICO image decoder for (1) gdk-pixbuf before 0.22 and (2) gtk2 before 2.2.4 allows remote attackers to cause a denial of service (application crash) via a crafted ICO file.

Integer overflow in camel-lock-helper in Evolution 2.0.2 and earlier allows local users or remote malicious POP3 servers to execute arbitrary code via a length value of -1, which leads to a zero byte memory allocation and a buffer overflow.

The patch for integer overflow vulnerabilities in Xpdf 2.0 and 3.0 (CVE-2004-0888) is incomplete for 64-bit architectures on certain Linux distributions such as Red Hat, which could leave Xpdf users exposed to the original vulnerabilities.

Integer overflow in io-xpm.c in gdk-pixbuf 0.22.0 in GTK+ before 2.8.7 allows attackers to cause a denial of service (crash) or execute arbitrary code via an XPM file with large height, width, and colour values, a different vulnerability than CVE-2005-3186.

Integer overflow in the GTK+ gdk-pixbuf XPM image rendering library in GTK+ 2.4.0 allows attackers to execute arbitrary code via an XPM file with a number of colors that causes insufficient memory to be allocated, which leads to a heap-based buffer overflow.

The cairo library (libcairo), as used in GNOME Evolution and possibly other products, allows remote attackers to cause a denial of service (persistent client crash) via an attached text file that contains "Content-Disposition: inline" in the header, and a very long line in the body, which causes the client to repeatedly crash until the e-mail message is manually removed, possibly due to a buffer overflow, as demonstrated using an XML attachment.

Stack-based buffer overflow in the ir_fetch_seq function in balsa before 2.3.20 might allow remote IMAP servers to execute arbitrary code via a long response to a FETCH command.

Format string vulnerability in the emf_multipart_encrypted function in mail/em-format.c in Evolution 2.12.3 and earlier allows remote attackers to execute arbitrary code via a crafted encrypted message, as demonstrated using the Version field.

The excel_read_HLINK function in plugins/excel/ms-excel-read.c in Gnome Office Gnumeric before 1.8.1 allows user-assisted remote attackers to execute arbitrary code via a crafted XLS file containing XLS HLINK opcodes, possibly because of an integer signedness error that leads to an integer overflow. NOTE: some of these details are obtained from third party information.

Buffer overflow in Evolution 2.22.1, when the ITip Formatter plugin is disabled, allows remote attackers to execute arbitrary code via a long timezone string in an iCalendar attachment.

Heap-based buffer overflow in Evolution 2.22.1 allows user-assisted remote attackers to execute arbitrary code via a long DESCRIPTION property in an iCalendar attachment, which is not properly handled during a reply in the calendar view (aka the Calendars window).

Format string vulnerability in the window_error function in yelp-window.c in yelp in Gnome after 2.19.90 and before 2.24 allows remote attackers to execute arbitrary code via format string specifiers in an invalid URI on the command line, as demonstrated by use of yelp within (1) man or (2) ghelp URI handlers in Firefox, Evolution, and unspecified other programs.

Format string vulnerability in the vinagre_utils_show_error function (src/vinagre-utils.c) in Vinagre 0.5.x before 0.5.2 and 2.x before 2.24.2 might allow remote attackers to execute arbitrary code via format string specifiers in a crafted URI or VNC server response.

Multiple directory traversal and buffer overflow vulnerabilities were discovered in yTNEF, and in Evolution's TNEF parser that is derived from yTNEF. A crafted email could cause these applications to write data in arbitrary locations on the filesystem, crash, or potentially execute arbitrary code when decoding attachments.

The FoFiType1::parse function in fofi/FoFiType1.cc in Xpdf 3.0.0, gpdf 2.8.2, kpdf in kdegraphics 3.3.1, and possibly other libraries and versions, does not check the return value of the getNextLine function, which allows context-dependent attackers to execute arbitrary code via a PDF file with a crafted Type 1 font that can produce a negative value, leading to a signed-to-unsigned integer conversion error and a buffer overflow.

Buffer overflow in the GMIME_UUENCODE_LEN macro in gmime/gmime-encodings.h in GMime before 2.4.15 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via input data for a uuencode operation.

Array index error in the hb_ot_layout_build_glyph_classes function in pango/opentype/hb-ot-layout.cc in Pango before 1.27.1 allows context-dependent attackers to cause a denial of service (application crash) via a crafted font file, related to building a synthetic Glyph Definition (aka GDEF) table by using this font's charmap and the Unicode property database.

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.
