– Ubuntu 18.04 LTS
– Ubuntu 16.04 LTS
– Ubuntu 14.04 LTS<\/p>\n
Summary:<\/p>\n
Several security issues were fixed in GNU C Library.<\/p>\n
Software Description:
– glibc: GNU C Library
– eglibc: GNU C Library<\/p>\n
Details:<\/p>\n
It was discovered that GNU C Library incorrectly handled netgroup requests.
An attacker could possibly use this issue to cause a crash or execute arbitrary code.
This issue only affected Ubuntu 14.04 LTS. (CVE-2014-9984)<\/p>\n
It was discovered that GNU C Library might allow context-dependent
attackers to cause a denial of service. This issue only affected Ubuntu 14.04 LTS.
(CVE-2015-20109)<\/p>\n
It was discovered that GNU C Library when processing very long pathname arguments to
the realpath function, could encounter an integer overflow on 32-bit
architectures, leading to a stack-based buffer overflow and, potentially,
arbitrary code execution. This issue only affected Ubuntu 14.04 LTS.
(CVE-2018-11236)<\/p>\n
It was discovered that the GNU C library getcwd function incorrectly
handled buffers. An attacker could use this issue to cause the GNU C
Library to crash, resulting in a denial of service, or possibly execute
arbitrary code. This issue only affected Ubuntu 14.04 LTS. (CVE-2021-3999)<\/p>\n
Charles Fol discovered that the GNU C Library iconv feature incorrectly
handled certain input sequences. An attacker could use this issue to cause
the GNU C Library to crash, resulting in a denial of service, or possibly
execute arbitrary code. (CVE-2024-2961)<\/p>\n
Update instructions:<\/p>\n
The problem can be corrected by updating your system to the following
package versions:<\/p>\n
Ubuntu 18.04 LTS
libc6 2.27-3ubuntu1.6+esm2
