Description Alexandros Toptsoglou 2019-08-01 10:11:19 UTC

CVE-2019-14378

A heap buffer overflow issue was found in the SLiRP networking implementation
of the QEMU emulator. It occurs in ip_reass() routine while reassembling
incoming packets, if the first fragment is bigger than the m->m_dat[] buffer. 

A user/process could use this flaw to crash the Qemu process on the host
resulting in DoS or potentially execute arbitrary code with privileges of the 
QEMU process.

Comment 23 Liang Yan 2020-07-23 20:19:19 UTC

@aginies, do we need to backport all our qemu versions? I thought LTSS only covers to 11sp3/11sp4.

Comment 24 Antoine Ginies 2020-07-28 08:29:18 UTC

We backport only on supported product. So nothing more than LTSS.
SLE11SP1 and SP2 are out of scope.

Comment 32 José Ricardo Ziviani 2021-07-23 19:41:11 UTC

Fix included in maintenance request for all affected releases. Returning to security-team.

Thank you!

Jose

Comment 33 Carlos López 2022-06-10 09:09:43 UTC
