Details

USN-6736-1 fixed vulnerabilities in klibc. This update provides the
corresponding updates for Ubuntu 24.04 LTS.

Original advisory details:

It was discovered that zlib, vendored in klibc, incorrectly handled pointer
arithmetic. An attacker could use this issue to cause klibc to crash or to
possibly execute arbitrary code. (CVE-2016-9840, CVE-2016-9841)

Danilo Ramos discovered that zlib, vendored in klibc, incorrectly handled
memory when performing certain deflating operations. An attacker could use
this issue to cause klibc to crash or to possibly execute arbitrary code.
(CVE-2018-25032)

Evgeny Legerov discovered that zlib, vendored in klibc, incorrectly handled
memory when performing certain inflate operations. An attacker could use
this issue to cause klibc to crash or to possibly execute arbitrary code.
(CVE-2022-37434)
