| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2017-12-01 | CVE-2017-16611 | Link Following vulnerability in multiple products In libXfont before 1.5.4 and libXfont2 before 2.0.3, a local attacker can open (but not read) files on the system as root, triggering tape rewinds, watchdogs, or similar mechanisms that can be triggered by opening files. | 4.9 |
| 2017-08-18 | CVE-2007-5199 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in X Libxfont 1.3.1 A single byte overflow in catalogue.c in X.Org libXfont 1.3.1 allows remote attackers to have unspecified impact. | 7.5 |
| 2015-03-20 | CVE-2015-1804 | Numeric Errors vulnerability in X Libxfont The bdfReadCharacters function in bitmap/bdfread.c in X.Org libXfont before 1.4.9 and 1.5.x before 1.5.1 does not properly perform type conversion for metrics values, which allows remote authenticated users to cause a denial of service (out-of-bounds memory access) and possibly execute arbitrary code via a crafted BDF font file. | 8.5 |
| 2015-03-20 | CVE-2015-1803 | Local Denial of Service vulnerability in X.Org libXfont 'bitmap/bdfread.c' The bdfReadCharacters function in bitmap/bdfread.c in X.Org libXfont before 1.4.9 and 1.5.x before 1.5.1 does not properly handle character bitmaps it cannot read, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and crash) and possibly execute arbitrary code via a crafted BDF font file. | 8.5 |
| 2015-03-20 | CVE-2015-1802 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in X Libxfont The bdfReadProperties function in bitmap/bdfread.c in X.Org libXfont before 1.4.9 and 1.5.x before 1.5.1 allows remote authenticated users to cause a denial of service (out-of-bounds write and crash) or possibly execute arbitrary code via a (1) negative or (2) large property count in a BDF font file. | 8.5 |
| 2014-05-15 | CVE-2014-0211 | Numeric Errors vulnerability in multiple products Multiple integer overflows in the (1) fs_get_reply, (2) fs_alloc_glyphs, and (3) fs_read_extent_info functions in X.Org libXfont before 1.4.8 and 1.4.9x before 1.4.99.901 allow remote font servers to execute arbitrary code via a crafted xfs reply, which triggers a buffer overflow. | 7.5 |
| 2014-05-15 | CVE-2014-0210 | Improper Restriction of Operations Within the Bounds of A Memory Buffer vulnerability in multiple products Multiple buffer overflows in X.Org libXfont before 1.4.8 and 1.4.9x before 1.4.99.901 allow remote font servers to execute arbitrary code via a crafted xfs protocol reply to the (1) _fs_recv_conn_setup, (2) fs_read_open_font, (3) fs_read_query_info, (4) fs_read_extent_info, (5) fs_read_glyphs, (6) fs_read_list, or (7) fs_read_list_info function. | 7.5 |
| 2014-05-15 | CVE-2014-0209 | Numeric Errors vulnerability in multiple products Multiple integer overflows in the (1) FontFileAddEntry and (2) lexAlias functions in X.Org libXfont before 1.4.8 and 1.4.9x before 1.4.99.901 might allow local users to gain privileges by adding a directory with a large fonts.dir or fonts.alias file to the font path, which triggers a heap-based buffer overflow, related to metadata. | 4.6 |
| 2014-01-09 | CVE-2013-6462 | Improper Restriction of Operations Within the Bounds of A Memory Buffer vulnerability in X Libxfont Stack-based buffer overflow in the bdfReadCharacters function in bitmap/bdfread.c in X.Org libXfont 1.1 through 1.4.6 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a long string in a character name in a BDF font file. | 9.3 |
| 2011-08-19 | CVE-2011-2895 | Improper Restriction of Operations Within the Bounds of A Memory Buffer vulnerability in multiple products The LZW decompressor in (1) the BufCompressedFill function in fontfile/decompress.c in X.Org libXfont before 1.4.4 and (2) compress/compress.c in 4.3BSD, as used in zopen.c in OpenBSD before 3.8, FreeBSD, NetBSD 4.0.x and 5.0.x before 5.0.3 and 5.1.x before 5.1.1, FreeType 2.1.9, and other products, does not properly handle code words that are absent from the decompression table when encountered, which allows context-dependent attackers to trigger an infinite loop or a heap-based buffer overflow, and possibly execute arbitrary code, via a crafted compressed stream, a related issue to CVE-2006-1168 and CVE-2011-2896. | 9.3 |
