EulerOS 2.0 SP3 : irssi (EulerOS-SA-2019-2595)

critical Nessus Plugin ID 132130

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the irssi package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- An issue was discovered in Irssi before 1.0.4. When receiving messages with invalid time stamps, Irssi would try to dereference a NULL pointer.(CVE-2017-10965)

- An issue was discovered in Irssi before 1.0.4. While updating the internal nick list, Irssi could incorrectly use the GHashTable interface and free the nick while updating it. This would then result in use-after-free conditions on each access of the hash table.(CVE-2017-10966)

- In Irssi before 1.0.3, when receiving a DCC message without source nick/host, it attempts to dereference a NULL pointer. Thus, remote IRC servers can cause a crash.(CVE-2017-9468)

- In Irssi before 1.0.3, when receiving certain incorrectly quoted DCC files, it tries to find the terminating quote one byte before the allocated memory.
Thus, remote attackers might be able to cause a crash.(CVE-2017-9469)

- In Irssi before 1.0.6, a calculation error in the completion code could cause a heap buffer overflow when completing certain strings.(CVE-2018-5208)

- Irssi before 0.8.21 allows remote attackers to cause a denial of service (out-of-bounds read and crash) via a string containing a formatting sequence (%[) without a closing bracket (]).(CVE-2017-5356)

- The nickcmp function in Irssi before 0.8.21 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a message without a nick.(CVE-2017-5193)

- Use-after-free vulnerability in Irssi before 0.8.21 allows remote attackers to cause a denial of service (crash) via an invalid nick message.(CVE-2017-5194)

- When the channel topic is set without specifying a sender, Irssi before 1.0.6 may dereference a NULL pointer.(CVE-2018-5206)

- When using an incomplete variable argument, Irssi before 1.0.6 may access data beyond the end of the string.(CVE-2018-5207)

- When using incomplete escape codes, Irssi before 1.0.6 may access data beyond the end of the string.(CVE-2018-5205)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected irssi packages.
