Description Robert Frohl 2019-11-08 08:20:56 UTC
CVE-2019-18397

Alex Murray discovered a stack-based buffer overflow vulnerability in
fribidi, an implementation of the Unicode Bidirectional Algorithm
algorithm, which could result in denial of service or potentially the
execution of arbitrary code, when processing a large number of unicode
isolate directional characters.
For the stable distribution (buster), this problem has been fixed in
version 1.0.5-3.1+deb10u1.
We recommend that you upgrade your fribidi packages.
For the detailed security status of fribidi please refer to its security
tracker page at:

Comment 1 Robert Frohl 2019-11-08 08:25:32 UTC
I believe we are not affected, because our version is too old.
Comment 2 Simon Logan 2021-01-18 16:23:53 UTC
Leap 15.2 has libfribidi0-1.0.5-lp152.1.3.x86_64.

lib/fribidi-bidi.c in libfribidi0-1.0.5-lp152.1.3.x86_64 appears to be missing the fix from https://github.com/fribidi/fribidi/commit/034c6e9a1d296286305f4cfd1e0072b879f52568

Do you plan to fix this in Leap 15.2?
Comment 3 Robert Frohl 2021-01-18 16:56:15 UTC
assigning to maintainer
Comment 4 Alexandros Toptsoglou 2021-01-19 14:38:56 UTC
SLE15-SP2 is also affected. The package in Leap is inherited by SLE
