Upgrade SLES:15.3
glibc-i18ndata
to version 2.31-9.3.2 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream glibc-i18ndata
package and not the glibc-i18ndata
package as distributed by SLES
.
See How to fix?
for SLES:15.3
relevant fixed versions and status.
The wordexp function in the GNU C Library (aka glibc) through 2.33 may crash or read arbitrary memory in parse_param (in posix/wordexp.c) when called with an untrusted, crafted pattern, potentially resulting in a denial of service or disclosure of information. This occurs because atoi was used but strtoul should have been used to ensure correct calculations.
