DEBIAN-CVE-2020-11743

An issue was discovered in Xen through 4.13.x, allowing guest OS users to cause a denial of service because of a bad error path in GNTTABOPmapgrant. Grant table operations are expected to return 0 for success, and a negative number for errors. Some misplaced brackets cause one error path to retur...

Bad error path in GNTTABOP_map_grant

ISSUE DESCRIPTION Grant table operations are expected to return 0 for success, and a negative number for errors. Some misplaced brackets cause one error path to return 1 instead of a negative value. The grant table code in Linux treats this condition as success, and proceeds with incorrectly...

UBUNTU-CVE-2019-15794

Overlayfs in the Linux kernel and shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu 5.0 and 5.3 kernel series, both replace vma-vmfile in their mmap handlers. On error the original value is not restored, and the reference is put for the file to which vmfile points. On...

CVE-2017-12133

CVE-2017-12133 affects the GNU C Library (glibc) prior to 2.26. It is a use-after-free in clntudp_call() in sunrpc/clnt_udp.c that allows remote attackers to potentially impact the target via error-path vectors. Affected products are glibc/libc6 environments prior to 2.26; remediation is to upgra...

libtiff: TIFFFlushData1 heap-buffer-overflow

tifwrite.c in libtiff 4.0.6 has an issue in the error code path of TIFFFlushData1 that didn't reset the tifrawcc and tifrawcp members. Reported as MSVR 35095, aka "TIFFFlushData1 heap-buffer-overflow."...

double free in curl_maprintf

The libcurl API function called curlmaprintf can be tricked into doing a double free due to an unsafe sizet multiplication, on systems using 32-bit sizet variables. The function is also used internally in numerous situations. The function doubles an allocated memory area with realloc and allows t...

xen-kernel -- use after free in FIFO event channel code

The Xen Project reports: When the EVTCHNOPinitcontrol operation is called with a bad guest frame number, it takes an error path which frees a control structure without also clearing the corresponding pointer. Certain subsequent operations EVTCHNOPexpandarray or another EVTCHNOPinitcontrol, upon...

arm: Host crash caused by VMID exhaustion

ISSUE DESCRIPTION VMIDs are a finite hardware resource, and allocated as part of domain creation. If no free VMIDs are available when trying to create a new domain, a bug in the error path causes a NULL pointer to be used, resulting in a Data Abort and host crash. IMPACT Attempting to create too...
