9.8 CVSS

Qt for Android prior to 5.9.0 allows remote attackers to execute arbitrary OS commands via unspecified vectors.

EPSS: 0.97%
7.5 CVSS

The named pipes in qtsingleapp in Qt 5.x, as used in qBittorrent and SugarSync, are configured for remote access and allow remote attackers to cause a denial of service (application crash) via an unspecified string.

EPSS: 0.83%
5.1 CVSS

ownCloud Desktop Client before 2.0.1, when compiled with a Qt release after 5.3.x, does not call QNetworkReply::ignoreSslErrors with the list of errors to be ignored, which makes it easier for remote attackers to conduct man-in-the-middle (MITM) attacks by leveraging a server using a self-signed certificate. NOTE: this vulnerability exists because of a partial CVE-2015-4456 regression.

EPSS: 0.25%
6.8 CVSS

Multiple buffer overflows in gui/image/qgifhandler.cpp in the QtBase module in Qt before 4.8.7 and 5.x before 5.4.2 allow remote attackers to cause a denial of service (segmentation fault) and possibly execute arbitrary code via a crafted GIF image.

EPSS: 6.36%
6.8 CVSS

Multiple buffer overflows in plugins/imageformats/ico/qicohandler.cpp in the QtBase module in Qt before 4.8.7 and 5.x before 5.4.2 allow remote attackers to cause a denial of service (segmentation fault and crash) and possibly execute arbitrary code via a crafted ICO image.

EPSS: 4.40%
6.8 CVSS

Multiple buffer overflows in gui/image/qbmphandler.cpp in the QtBase module in Qt before 4.8.7 and 5.x before 5.4.2 allow remote attackers to cause a denial of service (segmentation fault and crash) and possibly execute arbitrary code via a crafted BMP image.

EPSS: 2.57%
4.3 CVSS

The GIF decoder in QtGui in Qt before 5.3 allows remote attackers to cause a denial of service (NULL pointer dereference) via invalid width and height values in a GIF image.

EPSS: 1.08%
5.0 CVSS

QXmlSimpleReader in Qt before 5.2 allows context-dependent attackers to cause a denial of service (memory consumption) via an XML Entity Expansion (XEE) attack.

EPSS: 5.22%
6.8 CVSS

SQL injection vulnerability in Quassel IRC before 0.9.1, when Qt 4.8.5 or later and PostgreSQL 8.2 or later are used, allows remote attackers to execute arbitrary SQL commands via a \ (backslash) in a message.

EPSS: 0.67%
4.3 CVSS

The QSslSocket::sslErrors function in Qt before 4.6.5, 4.7.x before 4.7.6, 4.8.x before 4.8.5, when using certain versions of openSSL, uses an "incompatible structure layout" that can read memory from the wrong location, which causes Qt to report an incorrect error when certificate validation fails and might cause users to make unsafe security decisions to accept a certificate.

EPSS: 2.28%
