VUL-1: CVE-2021-3594: qemu,kvm,libslirp: slirp: invalid pointer initialization may lead to information disclosure (udp)
Last modified: 2023-08-04 11:22:09 UTC
An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The function udp_input() handles requests for the udp protocol from the guest. While processing a udp packet that is smaller than the size of the udphdr structure it uses memory from outside the working mbuf buffer. This issue may lead to out of bound read access or indirect memory disclosure to the guest.

Hello Security Team, Basically the same comment I did in 1187364 applies here. I backported the fix except to 15-SP3 and Factory because I understand that is another team taking care of it. Thank you Jose

Hi Ralf, can you please patch SUSE:SLE-15-SP3:Update/libslirp which is also affected? While openSUSE:Factory/libslirp is already patched. Thanks

I backported the > fix except to 15-SP3 and Factory because I understand that is another team > taking care of it. I'm not aware of this other maintainer, there still are two missing submissions for qemu. Could you please submit the patch to: - SUSE:SLE-11:Update - SUSE:SLE-15-SP3:Update @Coldpool: can you please submit the patch for SUSE:SLE-15-SP3:Update/libslirp ?
15sp3/libslirp submitted.
(In reply to Gianluca Gabrielli from comment #19) > - SUSE:SLE-15-SP3:Update Just looked on the qemu spec and changelog, it seems from there that it is using system libslirp from 15sp3 on, right?

You are correct, nice catch. @Jose: only SUSE:SLE-11:Update/qemu submission is missing

BTW, do we need to support SLE-11? It will be end of life until the end of next month.
(In reply to Gianluca Gabrielli from comment #23) > > @Jose: only SUSE:SLE-11:Update/qemu submission is missing > So, as discussed elsewhere (on another very similar bug), this will not be fixed in SLE-11's QEMU. Returning to Security Team.
