Here’s my (fourth) monthly update about the activities I’ve done in Debian this January.

Debian LTS

This was my fourth month as a Debian LTS paid contributor.
I was assigned 23.75 hours and worked on the following things:

CVE Fixes and Announcements:

  • Issued DLA 2060-1, fixing CVE-2020-5504, for phpmyadmin.
    Details here:

    In phpMyAdmin 4 before 4.9.4 and 5 before 5.0.1, SQL injection exists in the user accounts page. A malicious user could inject custom SQL in place of their own username when creating queries to this page. An attacker must have a valid MySQL account to access the server.

    For Debian 8 “Jessie”, this problem has been fixed in version 4:4.2.12-2+deb8u8.
    Furthermore, worked on preparing the security update for Stretch and Buster with the original maintainer.

  • Issued DLA 2063-1, fixing CVE-2019-3467 for debian-lan-config.
    Details here:

    In debian-lan-config < 0.26, configured too permissive ACLs for the Kerberos admin server allowed password changes for other Kerberos user principals.

    For Debian 8 “Jessie”, this problem has been fixed in version 0.19+deb8u2.

  • Issued DLA 2070-1, fixing CVE-2019-16779, for ruby-excon.
    Details here:

    In RubyGem excon before 0.71.0, there was a race condition around persistent connections, where a connection which is interrupted (such as by a timeout) would leave data on the socket. Subsequent requests would then read this data, returning content from the previous response.

    For Debian 8 “Jessie”, this problem has been fixed in version 0.33.0-2+deb8u1.
    Furthermore, sent a patch to the Security team for Stretch and Buster.

    P.S. this backporting took the most time and effort this month.

  • Issued DLA 2090-1, fixing CVE-2020-7039, for qemu.
    Details here:

    tcp_emu in tcp_subr.c in libslirp 4.1.0, as used in QEMU 4.2.0, mismanages memory, as demonstrated by IRC DCC commands in EMU_IRC. This can cause a heap-based buffer overflow or other out-of-bounds access which can lead to a DoS or potential execute arbitrary code.

    For Debian 8 “Jessie”, this problem has been fixed in version 1:2.1+dfsg-12+deb8u13.

Miscellaneous:

  • Triaged samba, cacti, storebackup, and qemu.

  • Checked with upstream of ruby-rack for their CVE fix which induces regression.

  • Worked a bit on ruby-rack-cors but couldn’t complete because of Amsterdam -> Brussels travel. Thanks to Brian for completing it \o/
