In Jasper 4.2.2 the jpcstreamlistremove function in src/libjasper/jpc/jpcdec.c:2407 has an assertion failure vulnerability allowing attackers to cause a denial of service attack through a specific image file.

Multiple format string vulnerabilities in the tolog function in httpdx 1.4, 1.4.5, 1.4.6, 1.4.6b, and 1.5 allow (1) remote attackers to execute arbitrary code via format string specifiers in a GET request to the HTTP server component when logging is enabled, and allow (2) remote authenticated users to execute arbitrary code via format string specifiers in a PWD command to the FTP server component.

The FTP server component in httpdx 1.4, 1.4.5, 1.4.6, 1.4.6b, and 1.5 has a default password of pass123 for the moderator account, which makes it easier for remote attackers to obtain privileged access.

A vulnerability was determined in JasPer up to 4.2.5. Affected by this issue is the function jpcfloorlog2 of the file src/libjasper/jpc/jpcenc.c of the component JPEG2000 Encoder. The manipulation leads to reachable assertion. The attack needs to be approached locally. The exploit has been disclosed to the public and may be used. The patch is identified as 79185d32d7a444abae441935b20ae4676b3513d4. It is recommended to apply a patch to fix this issue.

A vulnerability was identified in JasPer up to 4.2.5. This affects the function jpcdecdump of the file src/libjasper/jpc/jpcdec.c of the component JPEG2000 File Handler. The manipulation leads to use after free. An attack has to be approached locally. The exploit has been disclosed to the public and may be used. The patch is named 8308060d3fbc1da10353ac8a95c8ea60eba9c25a. It is recommended to apply a patch to fix this issue.

A vulnerability was found in JasPer up to 4.2.5. Affected by this vulnerability is the function jasimagechclrspc of the file src/libjasper/base/jasimage.c of the component Image Color Space Conversion Handler. The manipulation leads to null pointer dereference. It is possible to launch the attack on the local host. The exploit has been disclosed to the public and may be used. The identifier of the patch is bb7d62bd0a2a8e0e1fdb4d603f3305f955158c52. It is recommended to apply a patch to fix this issue.

httpdx 1.4.4 and earlier allows remote attackers to obtain the source code for a web page by appending a . (dot) character to the URI.

Stack-based buffer overflow in the hhandlepeer function in http.cpp in httpdx 1.4, and possibly 1.4.3, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long HTTP GET request.

Format string vulnerability in the hreadrequest function in http.c in httpdx Web Server 1.4 allows remote attackers to cause a denial of service (crash) or execute arbitrary code via format string specifiers in the Host header.

It was discovered that JasPer incorrectly handled certain malformed JPEG-2000 image files. If a user or automated system using JasPer were tricked into opening a specially crafted image, an attacker could exploit this to cause a denial of service or possibly execute code with the privileges of the user invoking the program.
