| CVE-2017-5196 | 1 Irssi | 1 Irssi | 2025-04-20 | 5.0 MEDIUM | 7.5 HIGH |
| Irssi 0.8.18 before 0.8.21 allows remote attackers to cause a denial of service (out-of-bounds read and crash) via vectors involving strings that are not UTF8. | |||||
| CVE-2017-10965 | 1 Irssi | 1 Irssi | 2025-04-20 | 7.5 HIGH | 9.8 CRITICAL |
| 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-2017-15721 | 2 Debian, Irssi | 2 Debian Linux, Irssi | 2025-04-20 | 5.0 MEDIUM | 7.5 HIGH |
| In Irssi before 1.0.5, certain incorrectly formatted DCC CTCP messages could cause a NULL pointer dereference. This is a separate, but similar, issue relative to CVE-2017-9468. | |||||
| CVE-2017-15228 | 1 Irssi | 1 Irssi | 2025-04-20 | 5.0 MEDIUM | 7.5 HIGH |
| Irssi before 1.0.5, when installing themes with unterminated colour formatting sequences, may access data beyond the end of the string. | |||||
| CVE-2017-15227 | 1 Irssi | 1 Irssi | 2025-04-20 | 5.0 MEDIUM | 7.5 HIGH |
| Irssi before 1.0.5, while waiting for the channel synchronisation, may incorrectly fail to remove destroyed channels from the query list, resulting in use-after-free conditions when updating the state later on. | |||||
| CVE-2017-5356 | 2 Debian, Irssi | 2 Debian Linux, Irssi | 2025-04-20 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2017-9468 | 2 Debian, Irssi | 2 Debian Linux, Irssi | 2025-04-20 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2017-7191 | 1 Irssi | 1 Irssi | 2025-04-20 | 7.5 HIGH | 9.8 CRITICAL |
| The netjoin processing in Irssi 1.x before 1.0.2 allows attackers to cause a denial of service (use-after-free) and possibly execute arbitrary code via unspecified vectors. | |||||
| CVE-2017-15723 | 2 Debian, Irssi | 2 Debian Linux, Irssi | 2025-04-20 | 5.0 MEDIUM | 7.5 HIGH |
| In Irssi before 1.0.5, overlong nicks or targets may result in a NULL pointer dereference while splitting the message. | |||||
| CVE-2016-7553 | 1 Irssi | 1 Buf.pl | 2025-04-20 | 2.1 LOW | 3.3 LOW |
| The buf.pl script before 2.20 in Irssi before 0.8.20 uses weak permissions for the scrollbuffer dump file created between upgrades, which might allow local users to obtain sensitive information from private chat conversations by reading the file. | |||||
| CVE-2017-10966 | 1 Irssi | 1 Irssi | 2025-04-20 | 7.5 HIGH | 9.8 CRITICAL |
| 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-2017-9469 | 2 Debian, Irssi | 2 Debian Linux, Irssi | 2025-04-20 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2017-5193 | 2 Debian, Irssi | 2 Debian Linux, Irssi | 2025-04-20 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2017-15722 | 2 Debian, Irssi | 2 Debian Linux, Irssi | 2025-04-20 | 4.3 MEDIUM | 5.9 MEDIUM |
| In certain cases, Irssi before 1.0.5 may fail to verify that a Safe channel ID is long enough, causing reads beyond the end of the string. | |||||
| CVE-2016-7044 | 3 Canonical, Debian, Irssi | 3 Ubuntu Linux, Debian Linux, Irssi | 2025-04-12 | 5.0 MEDIUM | 7.5 HIGH |
| The unformat_24bit_color function in the format parsing code in Irssi before 0.8.20, when compiled with true-color enabled, allows remote attackers to cause a denial of service (heap corruption and crash) via an incomplete 24bit color code. | |||||
| CVE-2016-7045 | 3 Canonical, Debian, Irssi | 3 Ubuntu Linux, Debian Linux, Irssi | 2025-04-12 | 5.0 MEDIUM | 7.5 HIGH |
| The format_send_to_gui function in the format parsing code in Irssi before 0.8.20 allows remote attackers to cause a denial of service (heap corruption and crash) via vectors involving the length of a string. | |||||
| CVE-2010-1155 | 1 Irssi | 1 Irssi | 2025-04-11 | 6.8 MEDIUM | N/A |
| Irssi before 0.8.15, when SSL is used, does not verify that the server hostname matches a domain name in the subject's Common Name (CN) field or a Subject Alternative Name field of the X.509 certificate, which allows man-in-the-middle attackers to spoof IRC servers via an arbitrary certificate. | |||||
| CVE-2010-1156 | 1 Irssi | 1 Irssi | 2025-04-11 | 4.3 MEDIUM | N/A |
| core/nicklist.c in Irssi before 0.8.15 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via vectors related to an attempted fuzzy nick match at the instant that a victim leaves a channel. | |||||
