1 CVE-2011-2895 119 Exec Code Overflow 2011-08-19 2012-05-11
9.3
 None Remote Medium Not required Complete Complete Complete
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.
2 CVE-2008-2476 20 DoS 2008-10-03 2009-03-25
9.3
 None Remote Medium Not required Complete Complete Complete

3 CVE-2007-1365 DoS Exec Code Overflow 2007-03-10 2008-09-05
10.0
 Admin Remote Low Not required Complete Complete Complete
Buffer overflow in kern/uipc_mbuf2.c in OpenBSD 3.9 and 4.0 allows remote attackers to execute arbitrary code via fragmented IPv6 packets due to "incorrect mbuf handling for ICMP6 packets." NOTE: this was originally reported as a denial of service.
4 CVE-2006-4304 DoS Exec Code Overflow +Info 2006-08-23 2008-09-05
10.0
 Admin Remote Low Not required Complete Complete Complete

5 CVE-2004-0492 DoS Exec Code Overflow 2004-08-06 2011-09-06
10.0
 Admin Remote Low Not required Complete Complete Complete
Heap-based buffer overflow in proxy_util.c for mod_proxy in Apache 1.3.25 to 1.3.31 allows remote attackers to cause a denial of service (process crash) and possibly execute arbitrary code via a negative Content-Length HTTP header field, which causes a large amount of data to be copied.
6 CVE-2004-0418 Exec Code 2004-08-06 2010-08-21
10.0
 Admin Remote Low Not required Complete Complete Complete
serve_notify in CVS 1.12.x through 1.12.8, and 1.11.x through 1.11.16, does not properly handle empty data lines, which may allow remote attackers to perform an "out-of-bounds" write for a single byte to execute arbitrary code or modify critical program data.
7 CVE-2004-0416 119 Exec Code Overflow 2004-08-06 2010-08-21
10.0
 Admin Remote Low Not required Complete Complete Complete
Double free vulnerability for the error_prog_name string in CVS 1.12.x through 1.12.8, and 1.11.x through 1.11.16, may allow remote attackers to execute arbitrary code.
8 CVE-2004-0414 DoS Exec Code 2004-08-06 2010-08-21
10.0
 Admin Remote Low Not required Complete Complete Complete
CVS 1.12.x through 1.12.8, and 1.11.x through 1.11.16, does not properly handle malformed "Entry" lines, which prevents a NULL terminator from being used and may lead to a denial of service (crash), modification of critical program data, or arbitrary code execution.
9 CVE-2004-0220 DoS 2004-05-04 2008-09-05
10.0
 None Remote Low Not required Complete Complete Complete
isakmpd in OpenBSD 3.4 and earlier allows remote attackers to cause a denial of service via a an ISAKMP packet with a malformed Cert Request payload, which causes an integer underflow that is used in a malloc operation that is not properly handled, as demonstrated by the Striker ISAKMP Protocol Test Suite.
10 CVE-2004-0084 Exec Code Overflow 2004-03-03 2010-08-21
