Libmobi 缓冲区错误漏洞

Libmobi is a C library . Used to handle Mobipocket/Kindle MOBI e-book format documents. An out-of-bounds read vulnerability exists in Libmobi, which stems from the program being vulnerable to the use of out-of-range pointer offsets, and can be exploited by an attacker to read memory information...

QEMU: usbredir: free() call on invalid pointer in bufp_alloc()

A flaw was found in the USB redirector device emulation of QEMU. It occurs when dropping packets during a bulk transfer from a SPICE client due to the packet queue being full. A malicious SPICE client could use this flaw to make QEMU call free with faked heap chunk metadata, resulting in a crash ...
