SUSE SLED15 / SLES15 / openSUSE 15 Security Update : libqt5-qtbase (SUSE-SU-2025:3723-1)

high Nessus Plugin ID 271225

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2025:3723-1 advisory.

 Security issues fixed:

 - CVE-2025-5455: processing of malformed data in `qDecodeDataUrl()` can trigger assertion and cause a crash (bsc#1243958).
 - CVE-2025-30348: complex algorithm used in `encodeText` in QDom when processing XML data can cause low performance (bsc#1239896).

 Other issues fixed:

 - Initialize a member variable in `QObjectPrivate::Signal` that was uninitialized under some circumstances.
 - Fix a crash when parsing a particular glyph in a particular font.
 - Avoid repeatedly registering xsettings callbacks when switching cursor themes.
 - Check validity of RandR output info before using it.
 - Fix reparenting a window so it takes effect even if there are no other state changes to the window.

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
