SUSE CVE-2014-1892

Xen 3.3 through 4.1, when XSM is enabled, allows local users to cause a denial of service via vectors related to a "large memory allocation," a different vulnerability than CVE-2014-1891, CVE-2014-1893, and CVE-2014-1894...

SUSE CVE-2014-1893

Multiple integer overflows in the 1 FLASKGETBOOL and 2 FLASKSETBOOL suboperations in the flask hypercall in Xen 4.1.x, 3.3.x, 3.2.x, and earlier, when XSM is enabled, allow local users to cause a denial of service processor fault via unspecified vectors, a different vulnerability than...

EulerOS Virtualization 2.9.0 : libxslt (EulerOS-SA-2022-2391)

According to the versions of the libxslt package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities : - Use after free in Blink XSLT in Google Chrome prior to 91.0.4472.164 allowed a remote attacker to potentially exploit heap...

CVE-2014-1892

CVE-2014-1892 relates to the Xen hypervisor (versions 3.3–4.1) with XSM enabled, where a local attacker can cause a denial of service via a reported “large memory allocation.” The connected records (SUSE advisories and OpenVAS entries) list CVE-2014-1892 among Xen-related advisories, confirming a...

CVE-2014-1891

CVE-2014-1891 affects the Xen hypervisor for multiple 4.x branches and older (3.2.x and earlier) when XSM is enabled. The issue is described as multiple integer overflows in the FLASK_GETBOOL, FLASK_SETBOOL, FLASK_USER, and FLASK_CONTEXT_TO_SID suboperations of the flask hypercall, enabling a loc...

CVE-2014-1893

Multiple integer overflows in the 1 FLASKGETBOOL and 2 FLASKSETBOOL suboperations in the flask hypercall in Xen 4.1.x, 3.3.x, 3.2.x, and earlier, when XSM is enabled, allow local users to cause a denial of service processor fault via unspecified vectors, a different vulnerability than...

CVE-2014-1893

The CVE-2014-1893 issue affects the Xen hypervisor (versions 4.1.x, 3.3.x, 3.2.x and earlier) where the FLASK_GETBOOL and FLASK_SETBOOL suboperations in the flask hypercall are vulnerable due to multiple integer overflows when XSM is enabled. This can allow a local user to trigger a denial of ser...

CVE-2014-1894

Multiple integer overflows in unspecified suboperations in the flask hypercall in Xen 3.2.x and earlier, when XSM is enabled, allow local users to cause a denial of service processor fault via unspecified vectors, a different vulnerability than CVE-2014-1891, CVE-2014-1892, and CVE-2014-1893...

Off-by-one error in FLASK_AVC_CACHESTAT hypercall

ISSUE DESCRIPTION The FLASKAVCCACHESTAT hypercall, which provides access to per-cpu statistics on the Flask security policy, incorrectly validates the CPU for which statistics are being requested. IMPACT An attacker can cause the hypervisor to read past the end of an array. This may result in...

integer overflow in several XSM/Flask hypercalls

ISSUE DESCRIPTION The FLASKGET,SETBOOL, FLASKUSER and FLASKCONTEXTTOSID suboperations of the flask hypercall are vulnerable to an integer overflow on the input size. The hypercalls attempt to allocate a buffer which is 1 larger than this size and is therefore vulnerable to integer overflow and an...

CVE-2013-1920

Xen 4.2.x, 4.1.x, and earlier, when the hypervisor is running "under memory pressure" and the Xen Security Module XSM is enabled, uses the wrong ordering of operations when extending the per-domain event channel tracking table, which causes a use-after-free and allows local guest kernels to injec...

Potential use of freed memory in event channel operations

ISSUE DESCRIPTION Wrong ordering of operations upon extending the per-domain event channel tracking table can cause a pointer to freed memory to be left in place, when the hypervisor is under memory pressure and XSM Xen Security Module is enabled. IMPACT Malicious guest kernels could inject...

Heap overflow
