GNU glibc ARMv7 memcpy() memory corruption vulnerability

Summary An exploitable signed comparison vulnerability exists in the ARMv7 memcpy implementation of GNU glibc. Calling memcpy on ARMv7 targets that utilize the GNU glibc implementation with a negative value for the ‘num’ parameter results in a signed comparison vulnerability. If an attacker...

CVE-2020-6096

A signed comparison vulnerability was found in GNU libc in the ARMv7 implementation of memcpy. The flaw affects the third argument to memcpy that specifies the number of bytes to copy. An underflow on the third argument could lead to undefined behavior such as out-of-bounds memory write and...

CVE-2020-6096

CVE-2020-6096

The CVE-2020-6096 entry is supported by connected sources: the glitch is in ARMv7 memcpy() within GNU glibc (version 2.30.9000 in the description) where underflowing the third parameter num can cause a signed-compare bug, potentially writing out of bounds and enabling remote code execution. Debia...

CVE-2016-6560

The CVE-2016-6560 family affects illumos via osnet-incorporation: bcopy() and bzero() implementati ons use signed rather than unsigned comparisons, leading to a NULL-pointer dereference / system crash. The impact described across sources is a crash vulnerability (denial of service). The available...

Integer overflow

Integer signedness error in system/core/adb/adbclient.c in Android Debug Bridge ADB for Android 4.4 in the Android SDK Platform Tools 18.0.1 allows ADB servers to execute arbitrary code via a negative length value, which bypasses a signed comparison and triggers a stack-based buffer overflow...

CVE-2011-2512

The virtioqueuenotify in qemu-kvm 0.14.0 and earlier does not properly validate the virtqueue number, which allows guest users to cause a denial of service guest crash and possibly execute arbitrary code via a negative number in the Queue Notify field of the Virtio Header, which bypasses a signed...
