CVE-2023-43786

Yair Mizrahi discovered an infinite recursion issue when parsing crafted XPM files, which would result in denial of service.

CVE-2023-43787

Yair Mizrahi discovered a buffer overflow vulnerability in libX11 when parsing crafted XPM files, which could result in denial of service or potentially the execution of arbitrary code.

CVE-2023-43788

Alan Coopersmith found an out of bounds read in XpmCreateXpmImageFromBuffer, which could result in denial of service when parsing crafted XPM files.

CVE-2023-43789

Alan Coopersmith discovered an out of bounds read issue when parsing corrupted colormaps, which could lead to denial of service when parsing crafted XPM files.

For Debian 10 buster, these problems have been fixed in version 1:3.5.12-1+deb10u2.

We recommend that you upgrade your libxpm packages.

For the detailed security status of libxpm please refer to its security tracker page at: [link moved to references]
