#buffer_overflow

flex.skl in Will Estes and John Millaway Fast Lexical Analyzer Generator (flex) before 2.5.33 does not allocate enough memory for grammars containing (1) REJECT statements or (2) trailing context rules, which causes flex to generate code that contains a buffer overflow that might allow context-dependent attackers to execute arbitrary code.

Multiple buffer overflows in htpasswd, as used in Acme thttpd 2.25b, and possibly other products such as Apache, might allow local users to gain privileges via (1) a long command line argument and (2) a long line in a file. NOTE: since htpasswd is normally installed as a non-setuid program, and the exploit is through command line options, perhaps this issue should not be included in CVE. However, if there are some typical or recommended configurations that use htpasswd with sudo privileges, or common products that access htpasswd remotely, then perhaps it should be included.

Multiple buffer overflows in STLport 5.0.2 might allow local users to execute arbitrary code via (1) long locale environment variables to a strcpy function call in c_locale_glibc2.c and (2) long arguments to unspecified functions in num_put_float.cpp.

zlib 1.2 and later versions allows remote attackers to cause a denial of service (crash) via a crafted compressed stream with an incomplete code description of a length greater than 1, which leads to a buffer overflow, as demonstrated using a crafted PNG file.

The Apache HTTP server before 1.3.34, and 2.0.x before 2.0.55, when acting as an HTTP proxy, allows remote attackers to poison the web cache, bypass web application firewall protection, and conduct XSS attacks via an HTTP request with both a "Transfer-Encoding: chunked" header and a Content-Length header, which causes Apache to incorrectly handle and forward the body of the request in a way that causes the receiving server to process it as a separate HTTP request, aka "HTTP Request Smuggling."

Buffer overflow in gram.y for PostgreSQL 8.0.0 and earlier may allow attackers to execute arbitrary code via a large number of arguments to a refcursor function (gram.y), which leads to a heap-based buffer overflow, a different vulnerability than CVE-2005-0247.

Multiple buffer overflows in Ipswitch WS_FTP Server 4.0.2 (1) allow remote authenticated users to execute arbitrary code by causing a large error string to be generated by the ALLO handler, or (2) may allow remote FTP administrators to execute arbitrary code by causing a long hostname or username to be inserted into a reply to a STAT command while a file is being transferred.

chat.ghp in Easy Chat Server 1.2 allows remote attackers to cause a denial of service (server crash) via a long username parameter, possibly due to a buffer overflow. NOTE: it was later reported that 2.2 is also affected.

Buffer overflow in Apache 2.0.50 and earlier allows local users to gain apache privileges via a .htaccess file that causes the overflow during expansion of environment variables.

The mod_dav module in Apache 2.0.50 and earlier allows remote attackers to cause a denial of service (child process crash) via a certain sequence of LOCK requests for a location that allows WebDAV authoring access.
