Directory traversal vulnerability in KArchive before 5.24, as used in KDE Frameworks, allows remote attackers to write to arbitrary files via a ../ (dot dot slash) in a filename in an archive file, related to KNewsstuff downloads.

kinit in KDE Frameworks before 5.23.0 uses weak permissions (644) for /tmp/xauth-xxx-_y, which allows local users to obtain X11 cookies of other users and consequently capture keystrokes and possibly gain privileges by reading the file.

daemon/Greeter.cpp in sddm before 0.13.0 does not properly disable the KDE crash handler, which allows local users to gain privileges by crashing a greeter when using certain themes, as demonstrated by the plasma-workspace breeze theme.

kde-workspace 4.2.0 and plasma-workspace before 5.1.95 allows remote attackers to obtain input events, and consequently obtain passwords, by leveraging access to the X server when the screen is locked.

kwalletd in KWallet before KDE Applications 14.12.0 uses Blowfish with ECB mode instead of CBC mode when encrypting the password store, which makes it easier for attackers to guess passwords via a codebook attack.

Multiple cross-site scripting (XSS) vulnerabilities in KDE-Runtime 4.14.3 and earlier, kwebkitpart 1.3.4 and earlier, and kio-extras 5.1.1 and earlier allow remote attackers to inject arbitrary web script or HTML via a crafted URI using the (1) zip, (2) trash, (3) tar, (4) thumbnail, (5) smtps, (6) smtp, (7) smb, (8) remote, (9) recentdocuments, (10) nntps, (11) nntp, (12) network, (13) mbox, (14) ldaps, (15) ldap, (16) fonts, (17) file, (18) desktop, (19) cgi, (20) bookmarks, or (21) ar scheme, which is not properly handled in an error message.

The KDE Clock KCM policykit helper in kde-workspace before 4.11.14 and plasma-desktop before 5.1.1 allows local users to gain privileges via a crafted ntpUtility (ntp utility name) argument.

KDE kdelibs before 4.14 and kauth before 5.1 does not properly use D-Bus for communication with a polkit authority, which allows local users to bypass intended access restrictions by leveraging a PolkitUnixProcess PolkitSubject race condition via a (1) setuid process or (2) pkexec process, related to CVE-2013-4288 and "PID reuse race conditions."

kio/usernotificationhandler.cpp in the POP3 kioslave in kdelibs 4.10.95 before 4.13.3 does not properly generate warning notifications, which allows man-in-the-middle attackers to obtain sensitive information via an invalid certificate.

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.

The image creation configuration in aaa_base before 16.26.1 for openSUSE 13.1 KDE adds the root user to the "users" group when installing from a live image, which allows local users to obtain sensitive information and possibly have other unspecified impacts, as demonstrated by reading /etc/shadow.

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.

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.

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."

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.

samples/powerbtn/powerbtn.sh in acpid (aka acpid2) 2.0.16 and earlier uses the pidof program incorrectly, which allows local users to gain privileges by running a program with the name kded4 and a DBUS_SESSION_BUS_ADDRESS environment variable containing commands.

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.

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.

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.

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.
