|---|---|---|---|---|---|---|
| CVE-2017-16611 | 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. | [email protected] | 5.5 | 0.42% | 2017-12-01 | 2026-05-13 |
| CVE-2007-5199 | A single byte overflow in catalogue.c in X.Org libXfont 1.3.1 allows remote attackers to have unspecified impact. | [email protected] | 9.8 | 2.21% | 2017-08-18 | 2026-05-13 |
| CVE-2015-1804 | 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. | [email protected] | 8.5 | 4.96% | 2015-03-20 | 2026-05-06 |
| CVE-2015-1803 | 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. | [email protected] | 8.5 | 4.90% | 2015-03-20 | 2026-05-06 |
| CVE-2015-1802 | 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. | [email protected] | 8.5 | 4.90% | 2015-03-20 | 2026-05-06 |
| CVE-2014-0211 | 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. | [email protected] | 7.5 | 4.36% | 2014-05-15 | 2026-05-06 |
| CVE-2014-0210 | 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. | [email protected] | 7.5 | 4.36% | 2014-05-15 | 2026-05-06 |
| CVE-2014-0209 | 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. | [email protected] | 4.6 | 0.44% | 2014-05-15 | 2026-05-06 |
| CVE-2013-6462 | 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. | [email protected] | 9.3 | 10.25% | 2014-01-09 | 2026-04-29 |
| CVE-2011-2895 | 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 | [email protected] | 9.3 | 8.36% | 2011-08-19 | 2026-04-29 |
