- More information:
Several vulnerabilities were found in QEMU, a fast processor emulator:
The rtl8139 emulator is affected by an integer overflow and subsequent buffer overflow. This vulnerability might be triggered by remote attackers with crafted packets to perform denial of service (via OOB stack buffer access).
The 9pfs subsystem is affected by a race condition allowing threads to modify an fid path while it is being accessed by another thread, leading to (for example) a use-after-free outcome. This vulnerability might be triggered by local attackers to perform denial of service.
The 9pfs subsystem is affected by a race condition during file renaming. This vulnerability might be triggered by local attackers to perform denial of service.
For Debian 8
Jessie, these problems have been fixed in version 1:2.1+dfsg-12+deb8u9.
We recommend that you upgrade your qemu packages.
