Multiple integer overflows in (1) OPVPOutputDev.cxx and (2) oprs/OPVPSplash.cxx in the pdftoopvp filter in CUPS and cups-filters before 1.0.47 allow remote attackers to execute arbitrary code via a crafted PDF file, which triggers a heap-based buffer overflow.
The OPVPWrapper::loadDriver function in oprs/OPVPWrapper.cxx in the pdftoopvp filter in CUPS and cups-filters before 1.0.47 allows local users to gain privileges via a Trojan horse driver in the same directory as the PDF file.
denyhosts 2.6 uses an incorrect regular expression when analyzing authentication logs, which allows remote attackers to cause a denial of service (incorrect block of IP addresses) via crafted login names.
rssh 2.3.2, as used by Debian, Fedora, and others, when the rsync protocol is enabled, allows local users to bypass intended restricted shell access via a (1) "-e" or (2) "--" command line option.
The simplexml_load_string function in the XML import plug-in (libraries/import/xml.php) in phpMyAdmin 3.4.x before 3.4.7.1 and 3.3.x before 3.3.10.5 allows remote authenticated users to read arbitrary files via XML data containing external entity references, aka an XML external entity (XXE) injection attack.
The png_format_buffer function in pngerror.c in libpng 1.0.x before 1.0.55, 1.2.x before 1.2.45, 1.4.x before 1.4.8, and 1.5.x before 1.5.4 allows remote attackers to cause a denial of service (application crash) via a crafted PNG image that triggers an out-of-bounds read during the copying of error-message data. NOTE: this vulnerability exists because of a CVE-2004-0421 regression. NOTE: this is called an off-by-one error by some sources.
Buffer overflow in libpng 1.0.x before 1.0.55, 1.2.x before 1.2.45, 1.4.x before 1.4.8, and 1.5.x before 1.5.4, when used by an application that calls the png_rgb_to_gray function but not the png_set_expand function, allows remote attackers to overwrite memory with an arbitrary amount of data, and possibly have unspecified other impact, via a crafted PNG image.
The png_err function in pngerror.c in libpng 1.0.x before 1.0.55, 1.2.x before 1.2.45, 1.4.x before 1.4.8, and 1.5.x before 1.5.4 makes a function call using a NULL pointer argument instead of an empty-string argument, which allows remote attackers to cause a denial of service (application crash) via a crafted PNG image.
The png_handle_sCAL function in pngrutil.c in libpng 1.0.x before 1.0.55, 1.2.x before 1.2.45, 1.4.x before 1.4.8, and 1.5.x before 1.5.4 does not properly handle invalid sCAL chunks, which allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impact via a crafted PNG image that triggers the reading of uninitialized memory.
ftpd.c in the GSS-API FTP daemon in MIT Kerberos Version 5 Applications (aka krb5-appl) 1.0.1 and earlier does not check the krb5_setegid return value, which allows remote authenticated users to bypass intended group access restrictions, and create, overwrite, delete, or read files, via standard FTP commands, related to missing autoconf tests in a configure script.
