CVE-2022-39046 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:22.10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream glibc package and not the glibc package as distributed by Ubuntu.
An issue was discovered in the GNU C Library (glibc) 2.36. When the syslog function is passed a crafted input string larger than 1024 bytes, it reads uninitialized memory from the heap and prints it to the target log file, potentially revealing a portion of the contents of the heap.
