[asterisk-bugs] [JIRA] (ASTERISK-25122) Large SIP packet received via pjsip over websocket crashes Asterisk

[Ivan Poddubny (JIRA)]

     [ https://issues.asterisk.org/jira/browse/ASTERISK-25122?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ivan Poddubny updated ASTERISK-25122:
-------------------------------------

    Description: 
A regression introduced in 13.2.0 causes a crash when pjsip receives a SIP packet over websocket that is larger than PJSIP_MAX_PKT_LEN. The packet is truncated but the len field in pkg_info is not, thus leading to memory corruption and a segfault.

The patch is up for review at https://gerrit.asterisk.org/#/c/528/
