xpdf: array indexing error in FoFiType1::parse()

The FoFiType1::parse function in fofi/FoFiType1.cc in the PDF parser in xpdf before 3.02pl5, poppler 0.8.7 and possibly other versions up to 0.15.1, kdegraphics, and possibly other products allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a PDF file with a crafted PostScript Type1 font that contains a negative array index, which bypasses input validation and triggers memory corruption.

kdelibs: partially universal XSS in Konqueror error pages

Cross-site scripting (XSS) vulnerability in the KHTMLPart::htmlError function in khtml/khtml_part.cpp in Konqueror in KDE SC 4.4.0 through 4.6.1 allows remote attackers to inject arbitrary web script or HTML via the URI in a URL corresponding to an unavailable web site.

kdenetwork: incomplete fix for CVE-2010-1000

Directory traversal vulnerability in the KGetMetalink::File::isValidNameAttr function in ui/metalinkcreator/metalinker.cpp in KGet in KDE SC 4.6.2 and earlier allows remote attackers to create arbitrary files via a .. (dot dot) in the name attribute of a file element in a metalink file. NOTE: this vulnerability exists because of an incomplete fix for CVE-2010-1000.

kdeutils: Ark path traversal

Directory traversal vulnerability in Ark 4.7.x and earlier allows remote attackers to delete and force the display of arbitrary files via .. (dot dot) sequences in a zip file.

kdelibs: input validation failure in KSSL

The KDE SSL Wrapper (KSSL) API in KDE SC 4.6.0 through 4.7.1, and possibly earlier versions, does not use a certain font when rendering certificate fields in a security dialog, which allows remote attackers to spoof the common name (CN) of a certificate via rich text.

kdepim: message viewer defaults to enabling java, javascript, and plugins

The HTMLQuoteColorer::process function in messageviewer/htmlquotecolorer.cpp in KDE PIM 4.6 through 4.8 does not disable JavaScript, Java, and Plugins, which allows remote attackers to inject arbitrary web script or HTML via a crafted email.

kdelibs: Heap-based buffer over-read when calculating dimensions of the canvas within the scale loop

khtml/imload/scaledimageplane.h in Konqueror in KDE 4.7.3 allows remote attackers to cause a denial of service (crash) and possibly read memory via large canvas dimensions, which leads to an unexpected sign extension and a heap-based buffer over-read.

(khtml): NULL pointer dereference when trying to reuse a frame with null part

rendering/render_replaced.cpp in Konqueror in KDE before 4.9.3 allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted web page, related to "trying to reuse a frame with a null part."

kdelibs: Use-after-free when context menu being used whilst the document DOM is being changed from within JavaScript

Use-after-free vulnerability in khtml/rendering/render_replaced.cpp in Konqueror in KDE 4.7.3, when the context menu is shown, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by accessing an iframe when it is being updated.

kdelibs: prints passwords contained in HTTP URLs in error messages

kioslave/http/http.cpp in KIO in kdelibs 4.10.3 and earlier allows attackers to discover credentials via a crafted request that triggers an "internal server error," which includes the username and password in an error message.

kde-workspace: NULL pointer dereference in KDM and KCheckPass when glibc 2.17 or FIPS-140 enabled system used

KDE-Workspace 4.10.5 and earlier does not properly handle the return value of the glibc 2.17 crypt and pw_encrypt functions, which allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via (1) an invalid salt or a (2) DES or (3) MD5 encrypted password, when FIPS-140 is enable, to KDM or an (4) invalid password to KCheckPass.

kdebase: race condition may allow local attackers to bypass screen locking

Race condition in workspace/krunner/lock/lockdlg.cc in the KRunner lock module in kdebase in KDE SC 4.4.0 allows physically proximate attackers to bypass KScreenSaver screen locking and access an unattended workstation by pressing the Enter key at a certain time, related to multiple forked processes.

In kdeconnect-kde (aka KDE Connect) before 20.08.2, an attacker on the local network could send crafted packets that trigger use of large amounts of CPU, memory, or network connection slots, aka a Denial of Service attack.

messagepartthemes/default/defaultrenderer.cpp in messagelib in KDE Applications before 18.12.0 does not properly restrict the handling of an http-equiv="REFRESH" value.

The HTML thumbnailer plugin in KDE Applications before 18.12.0 allows attackers to trigger outbound TCP connections to arbitrary IP addresses, leading to disclosure of the source IP address.

kde-workspace: DoS due memory leak in plasma desktop when handling blinking system tray icons

kde-workspace before 4.10.5 has a memory leak in plasma desktop

kdelibs: Heap-based buffer overflow when parsing location of a font face source

The CSS parser (khtml/css/cssparser.cpp) in Konqueror in KDE 4.7.3 allows remote attackers to cause a denial of service (crash) and possibly read memory via a crafted font face source, related to "type confusion."
